"Sometimes I wish one line blocks for if-else statements didn't require brackets..."

I use to say the same thing until i realized they don't: 
print "that's the answer" if $answer == 42;

die "that's not your file!" unless -o $file;

A caveat i teach my C++ lab students (i am a graduate teaching assistant at MTSU) is that even though braces are optional for one line blocks, they should get in the habit of using them always. Why? Because 9 times outta 10 you will want to add a second line in the near future. Murphy's law or something ... ;)
