...those semicolons aren't necessary either (nor are the braces, now that I think about it).
You're correct about the semicolons, but the braces are necessary. The if-else construct in Perl controls BLOCKs, not statements. Take a look at perldoc:perlsyn. This avoids the dangling-else ambiguity.

Don't confuse this with the if modifier, which comes at the end of statements, not BLOCKs.

I'll let good brother tilly take you to task for (probably inadvertently) passing your current @_ when calling yes and no. ;-)

    There is no need. Brother VSarkiss already did it for me. :-)

    -- edit: adding an interjection: D'oh!

    Well spotted..

    That's another reason to code defensively. Idioms don't necessarily port between languages, and even silence can mean something in the right place.

    FWIW, passing the current @_ is at least syntactically valid, and like so much of Perl, can be used for good or evil at one's own discretion.
