It only changes semantics of Scheme programs that are recursive in appearance. In non-recursive Scheme functions (those that don't loop and are not mutually recursive), it's merely an optimization, just as it is in C. Edit: Added mutual recursion explicitly.

Well, any program that neither loops nor is recursive (the same thing in Scheme), only has a very finite runtime. So those are not very interesting Scheme programs, I guess?

Except unlike C, it is a required feature.
