My personal preference would be for all such properties (traits?) to be
reserved across all types - eg using 'prompt' on a hash gives a
compile/run time error. This allows the compiler to catch certain types
of typo and thinko, and also allows us to expand in future - eg when
some P6Per comes up with a bright idea on how prompts can be made
applicable to hashes, we dont have the familar argument "but we can't
do that, it may break code that defines a user property called
'prompt'".
PS - I *really* like the traits proposal.
