Question

Teaching myself Perl with Project Euler. Anywho,

print "Hei" if 1==1;

works like a charm.

Is it possible to include several statements before the if, like so

{print "4";print="2";} if 4!=2;

I’m aware that specific syntax does not work, but I think what I want to do is obvious. Possible or not?

Ps. I’m also aware I could do this with a regular

if(){}

Answer 1

Simply add a do before it:

do {print "4";print="2";} if 4!=2;

Note that I wouldn’t recommend this kind of code in any real-life scenario. The normal

if (condition)
{
    code;
}

form is much more familiar, easier to read and debug, and has indentation to guide the reader regarding the flow of control.
