Ordinarily you'd test for subs with one of

I thought that was now spelt exists %Main::{&foo} -- that the symbol

testing for hashkey existance -- %hash{key}.exists should get the key
element of hash, then run it's exists method, logicly. Is it
%hash.exists('key')?
I suppose one could set up a transactional structure in which "can"
actually does the side effects hypothetically, with the option of
committing later. Sort of what a "try" block would like to be when
it grows up...
Or hypothetical variables in a non-regex context...
