There is a single entry/exit point. Apart from it being simple, I know that this makes it easier for compilers/interpreters to prove certain things about your code.

Maybe for a really stupid compiler, but I have trouble believing any modern optimizing compiler has trouble with escape analysis of this sort these days.
