Deprecating to me means, there's an advantage to remove it from the
language. I fail to see what the advantage would be. Do you have a better
of what 'sub foo {last}' could do? Would it make the implementation
faster?

It sounds too much like "I don't like it - let's deprecate it" to me.
Well, we have perl6-language for that (except that's more "I don't like
it - let's remove it").
