Glivter:   Further to haukex's reply:   In certain cases, I find  ? : ternary chains (update: I've also seen them referred to as "ladders") very neat, clear, readable and maintainable, and useful: 

my $result =
    CONDITION1 ? EXPRESSION1 :  # "if" case
    CONDITION2 ? EXPRESSION2 :  # "elsif" case
    CONDITION3 ? EXPRESSION3 :  # ditto
    ...                         # and so on...
    die "no condition met... "  # "else" default case
    ;

And, of course, you don't have to die or take any other drastic action in the default case, but simply return a default value. Your EXPRESSION can also be a side-effect-possessing  do { ... } expression or subroutine call that returns a meaningful value. (A do-block or subroutine call always returns a value, but if you don't design it right, that value may be surprising.)
