To shed my vast light on the discussion, 8 years later: Is this
replacing the current subroutine via a goto &othersub (rare),
really true? I thought that goto
was the only way to get proper tail-call recursion, which means that those of us with functional backgrounds who aren't so fond of iteration would be using it a lot.
Incidentally, nothingmuch has recently offered Sub::Call::Tail for those who recoil from the syntactic ugliness of the goto-based set-up. Given your contributions in the past, I imagine you have your own way of twisting tail-calling gotos into shape when the occasion warrants. :-)
