These are good suggestions. I'm not going to take them all: I like that it's UNIX-specific, and I like that it can use strict, and I don't like the warn output. (Though I'll point out that if you use warn you can dispense with the ".$/".) I think I'll use this version: 
/usr/bin/perl '-lefor(my$x=1;;){map$x%$_||next,2..$x++;print$x}'

And the golfiest version is 
for($x=1;;){map$x%$_||next,2..$x++;warn$x}
