This would allow a shorter way to say:
sub a(@A where .are ~~ Int) { }
namely:
sub a(@A where .are(Int)) { }
Further advantages:
- shortcircuiting as soon as an offending type is encountered
- instead of returning False, return a Failure with more error information
such as expected / gotten type *and* the element number that offended
After this, we'd only need to make X::TypeCheck::Binding::Parameter
actually show the message of the Failure, instead of "anonymous constraint
to be met".
