[vJASS] Returns boolean -vs- nothing

[Mr_Bean]

Hi guys,

I have seen many people make functions return a boolean for no reason. I seem to remember something about it being better, but I can't remember why. Could someone explain why it is preferred to return a boolean over return nothing. For example:

private function KillAll takes nothing returns boolean
    for enumU in enumG
        call KillUnit(enumU)
    endfor
    
    return true
endfunction

Thanks,

Mr_Bean

In the past there was a desycn if there were mac users in the case you used a return nothing function while a boolean was expected. (boolexpr)
It seems to be fixed now, but if you're afraid you still can use return boolean.

Oh okay. Well I'm not a Mac user and I'm not afraid, so I think I will just return nothing
Thanks!

But your code could end in a mac so it's advisable to follow the correct return.

Most of us thought it would not compile (crash / syntax error)... If you fail to push a value when one was excpected usually bad things happen.
