optimization - Is Perl optimized to skip remaining logic operands if the answer is already decided?

Question

For instance, I need to match some text if $do eq 'b'. If I run this code:

if (($do eq 'b') && (/text/))
{
do stuff
}

Would perl evaluate the first parenthesis and second parenthesis no matter what or would it stop at the evaluation of the second parenthesis if the first parenthesis was false?

Follow-up question here. (I didn't know if I should make a new question or post it here)

Answer 1

Yes. This behavior is commonly used in idiomatic perl.

Consider:

open FILE, ">$fname" or die $!;

If there is no error opening the file (open returns true), the die statement is not executed. This is not special treatment of the die routine; it is just the way perl handles logic evaluation.
