eval correct? (Score:1)
In your question you wrote:
I don't see that happening with just this line:
The "return" will return the value of "thatroutine()" outside the "eval", but it won't cause the inclosing subroutine to return, if I read the docs correctly. What am I missing?
Anyway, I usually prefer a simple, readable solution, one that doesn't depend on the short-circuit behaviour of "&&" and relatives (not everyone groks such code), even if it is a little more verbose. How about:

Sorry, but that's a very poor reason to avoid the short circuit behaviour of boolean ops. Programmers worth their salt must know about it, it such a basic tool, so helpful tool for improving legibility, and so widespread among languages. Without flinching I will go so far as to suggest that those who really cannot figure it out even after explanations, possibly repeated, shouldn't be touching code in the first place.
