MANUAL
Type::Tiny Stability Policy
Type::Tiny 1.000000+ is considered stable. Any changes to the API that
are big enough to require changes to the test suite will be preceded by
a six month notice period, with the following exceptions:
o Any changes which are necessary to maintain compatibility with new
releases of Moose, Moo, and other software that Type::Tiny needs to
integrate with.
o Changes to maintain compatibility with future versions of Perl
itself.
o Where a change fixes a contradiction between the implementation and
documentation of Type::Tiny.
o Where a feature is explicitly documented as being "experimental" or
"unstable".
o Improvements to the text of error messages.
Experimental and Unstable Type::Tiny Features
The following list is currently non-exhaustive.
o The following type checks result may vary based on your version of
Perl and whether Type::Tiny::XS is installed. Their outcome is
currently considered undefined, and may change in future versions.
o Using Object and similar type checks on unblessed regular
expression references, the outcome is undefined.
o On all current versions of Perl, false ("!!0") stringifies to
the empty string (but using Devel::Peek you can tell the
difference between this value and a normal empty string), so
Int and subtypes of Int do not consider it to be an integer. If
Perl's behaviour ever changes, you might not be able to rely on
this outcome. True ("!!1") stringifies as "1", so is considered
an integer.
o A glob (not a globref but an actual glob) currently passes the
StringLike type constraint but not the Str type constraint.
o The BoolLike type is intended to extend Bool to cover
overloaded boolean objects, but the exact mechanism it uses may
change.
o Type::Tiny's "my_methods" attribute and the functionality it
provides is experimental.
o The parameterizable coercion API is subject to change.
o The interaction of deep coercions and mutable coercions currently
results in ill-defined behaviour. This could change at any time.
o Type::Registry's ability to import MooseX::Types and MouseX::Types
type libraries is experimental.
o The "signature_for_func" and "signature_for_method" keywords
provided by Type::Params may change their behaviour slightly in the
future. Once stable, they are expected to be added to
Types::Common's exports.
o The "Types::Standard::Dict::combine" function.
o These modules are considered part of Type::Tiny's internals, and
not covered by the stability policy: Devel::TypeTiny::Perl58Compat,
Type::Coercion::FromMoose, Type::Params::Alternatives,
Type::Params::Parameter, Type::Params::Signature,
Type::Tiny::_HalfOp, Types::Standard::ArrayRef,
Types::Standard::CycleTuple, Types::Standard::Dict,
Types::Standard::HashRef, Types::Standard::Map,
Types::Standard::ScalarRef, Types::Standard::StrMatch,
Types::Standard::Tied, and Types::Standard::Tuple.
o The use of some of the modules in the previous list item as
exporters of shortcuts for parameterized types is not stable yet.
o Reply::Plugin::TypeTiny is not covered by the stability policy.
Type::Tiny Versioning Policy
As of 1.000000, this distribution follows a versioning scheme similar
to Moo, which is based on a semver <http://semver.org/>-like three
component version number, but with the last two components each
represented by three decimal digits in the fractional part of the
version number. That is, version 1.003002 of the software represents
"1.3.2".
Additionally, releases where the second component is an odd number will
be considered unstable/trial releases. (These will also include an
underscore in the version number as per the usual CPAN convention.)
Perl Version Support
Type::Tiny 0.000_01 to Type::Tiny 0.015_04 required Perl 5.8.1.
Type::Tiny 0.015_05+ and Type::Tiny 1.000000+ requires Perl 5.6.1.
Type::Tiny 2.000000+ will require Perl 5.8.1.
