Hm. Python's try/finally has several uses in virtually every program.

Trouble is, Scheme's continuations make it impossible to know when
something is really final. In fact, implementing coroutines and
cooperative multitasking using continuations almost guarantee a repeated
back-and-forth through dynamic-wind.

I strongly suspect Scheme's continuations are more trouble than they are
worth.
