Hi, I think it is good to have foreach and for loop even tough they are the same if you are searching in a file you can almost make a sentence foreach $line(@infile) #<-- to me this is more readable than for $line(@infile) But for loop, I use it only for numbers for(1..53) or for( $i=0;$i<50;$i++); it is also close to c++ so the transition from one language to another is tiny bit easier. This is my little point of view.
