Nothing ever wants the value of an if statement.

A plain if? Probably not. An if/elsif/else statement though?

my @classifications = map {
  if     ($_ > 0)  { 'positive' }
  elsif  ($_ < 0)  { 'negative' }
  else             { 'zero'     }
} @numbers;

Yes, you can write that using the ternary operator, but if/elsif/else can sometimes be clearer.
