Re^2: Re (tilly) 4: Paradigm Shift - when to use goto

[JadeNB]

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. :-)

Tail-call recursion simulation with goto in perl is pretty slow. See Pure Perl tail call optimization. It's supposed to be better optimized (don't know if it is yet) in Perl 6.
