No, I think the OP's point was NOT about assining an expression in a 
conditional statement, but a literal. That's why _lint_ was made to find 
out such things for C programmers.

BTW, I'm of the opinion that these kinds of warnings and, or error 
checking should be avoided in an interpreter; it better we too write a 
Ruby lint.
