Quite regularly in Python, despite the stack limitation. Why? It's sometimes the only elegant way to walk over small tree-like data structures, the depth of which you can be safely assured will never approach Python inbuilt limit (and if they did, it would always be a data error that should fail anyways). I do wish Python had Perl-style tail-recursion though.
