Type::Parser - parse type constraint strings
use v5.10;

use Type::Registry;
my $reg = Type::Registry->for_me;
$reg->add_types("Types::Standard");

This module is covered by the
Type-Tiny stability policy.
Generally speaking, you probably don't want to be using this module directly.
Instead use the lookup method from the Type::Registry manpage which wraps it.
- parse($string)
-
Parse the type constraint string into something like an AST.
If called in list context, also returns any ``tail'' found on the original string.
- extract_type($string, $registry)
-
Compile a type constraint string into a the Type::Tiny manpage object.
If called in list context, also returns any ``tail'' found on the original string.
- eval_type($string, $registry)
-
Compile a type constraint string into a the Type::Tiny manpage object.
Throws an error if the ``tail'' contains any non-whitespace character.
The following constants correspond to values returned by $token->type .
