=head1 NAME
MooseX::Types::Util - Common utility functions for the distribution
=head1 VERSION
version 0.41
=head1 DESCRIPTION
This package the exportable functions that many parts in
L<MooseX::Types> might need.
=head1 FUNCTIONS
=head2 filter_tags
Takes a list and returns two references. The first is a hash reference
containing the tags as keys and the number of their appearance as values.
The second is an array reference containing all other elements.
=head2 has_available_type_export
TypeConstraint | Undef = has_available_type_export($package, $name);
This function allows you to introspect if a given type export is available
I<at this point in time>. This means that the C<$package> must have imported
a type constraint with the name C<$name>, and it must be still in its symbol
table.
Two arguments are expected:
=over 4
=item $package
The name of the package to introspect.
=item $name
The name of the type export to introspect.
=back
B<Note> that the C<$name> is the I<exported> name of the type, not the declared
one. This means that if you use L<Sub::Exporter>s functionality to rename an import
like this:
use MyTypes Str => { -as => 'MyStr' };
you would have to introspect this type like this:
has_available_type_export $package, 'MyStr';
The return value will be either the type constraint that belongs to the export
or an undefined value.
