Because the others are clueless?

It is interesting to note that GNU C supports closures, just not with
indefinite extent. It's a very nice feature that I would use a lot,
if it wasn't for 1) it makes my code less portable and 2) I'm scared
of the performance hits from the cache flushes that may need to
accompany the trampoline generation on the stack. But it has no
problem with mutating bindings in lexical scope, unlike Python.
