=head1 NAME

Specio::Library::Perl - Implements type constraint objects for some common Perl language things

=head1 VERSION

version 0.46

=head1 DESCRIPTION

This library provides some additional string types for common cases.

=head2 PackageName

A valid package name. Unlike the C<ClassName> constraint from the
L<Specio::Library::Builtins> library, this package does not need to be loaded.

This type does allow Unicode characters.

=head2 ModuleName

Same as C<PackageName>.

=head2 DistName

A valid distribution name like C<DBD-Pg> Basically this is the same as a
package name with the double-colons replaced by dashes. Note that there are
some historical distribution names that don't fit this pattern, like
C<CGI.pm>.

This type does allow Unicode characters.

=head2 Identifier

An L<Identifier|perldata/Variable names> is something that could be used as a
symbol name or other identifier (filehandle, directory handle, subroutine
name, format name, or label). It's what you put after the sigil (dollar sign,
at sign, percent sign) in a variable name. Generally, it's a bunch of
word characters not starting with a digit.

This type does allow Unicode characters.

=head2 SafeIdentifier

This is just like an C<Identifier> but it excludes the single-character
variables underscore (C<_>), C<a>< and C<b>, as these are special variables to
the Perl interpreter.

=head2 LaxVersionStr and StrictVersionStr

Lax and strict version strings use the L<is_lax|version/is_lax> and
L<is_strict|version/is_strict> methods from C<version> to check if the given
string would be a valid lax or strict version. L<version::Internals> covers
the details but basically: lax versions are everything you may do, and strict
omit many of the usages best avoided.

=head2 CREDITS

Much of the code and docs for this library comes from MooseX::Types::Perl,
written by Ricardo SIGNES <rjbs@cpan.org>.

I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
