-excludes instead. (Dave Rolsky)
[ENHANCEMENTS]
When composing one role into another and there is an attribute conflict,
the error message now includes the attribute name. Reported by Sam
Graham. RT #59985. (Dave Rolsky)When a class is made immutable, the does_role method is overridden with a
much faster version that simply looks role names up in a hash. Code which
uses lots of role-based type constraints should be faster. (Dave Rolsky)
