Can you give me an example where the two return different values?
When condition() is truthy, the first evaluates to True and the second evaluates to [] Try it out. https://ideone.com/GciAs8
True and False or 5

Also worth remembering that a perl statement can be converted into an expression with a do block, so you can write my $x = do { if (foo()) { 4 } else { 5 } }; (and yes, I know, that example would look fine as a ternary - but this is meant to illustrate the syntax possibility, not where I'd specifically use it - and once the logic within one of the two conditional branches gets more complicated, switching to do+if+els…
What the... ? Why is that worth remembering? Just reading that code makes me feel dirty, let alone deploying it! ;-)
Also doing that with if/elsif/elsif/else is often far more readable than nested/chained ternaries.
