Perl also has a conditional-statement almost like C's. There are some 
differences. Its syntax is if (a) {b} else {c} instead of if (a) b; else 
c; because Perl has no separate concept of compound statement.

And then also Perl has more different implicit conversions to bool than C 
has.

The if-statement is remarkably uniform across different languages, in a 
way that the for-loop and the switch-statement aren't.

The biggest difference you will see, is that some if-statements are 
actually if-expressions instead. This is the case with if(,,) in the 
[expr] class. This is also the case with a?b:c in C language. It's the 
case with if/then/else/end in Ruby and the if {} {} {} in Tcl.

Perl is somewhat in-between because although you can't assign the result 
of an if-statement to a variable, you can return it from a function, but 
that's because Perl uses the value of the last executed statement as the 
default return value.
