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 Type::Registry 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, $registry)
Compile a type constraint string into a Type::Tiny object.
If called in list context, also returns any "tail" found on the original string.
eval_type($string, $registry)
Compile a type constraint string into a Type::Tiny object.
Throws an error if the "tail" contains any non-whitespace character.
The following constants correspond to values returned by $token->type
.

QUOTELIKE
