Thanks about return. That means I need replace:
return $map[$yCur-1][$xCur-1] eq $wall;
with
return if!($map[$yCur-1][$xCur-1] eq $wall);?
but when are you realy going to have a truth in list context? hmm I wounder is perl6 with have a list function....

I don't know much about grep but that apears to be equivalent to 
if(
&test2($xCur, $yCur, $wall) && 
&test3($xCur, $yCur, $wall) && 
&test4($xCur, $yCur, $wall) && 
&test5($xCur, $yCur, $wall) && 
&test6($xCur, $yCur, $wall) && 
&test7($xCur, $yCur, $wall) && 
&test8($xCur, $yCur, $wall))
