-
-Given a $string that is the parameter information part of a parameterized
-constraint, parses it for internal constraint information. For example:
-
- MyType[Int,Int,Str]
-
-has a parameter string of "Int,Int,Str" (whitespace will automatically be
-removed during normalization that happens in L<Moose::Util::TypeConstraints>)
-and we need to convert that to ['Int','Int','Str'] which then has any type
-constraints converted to true objects.
