(would you?).

Actually, I quite often find that the first of these two is exactly what I want as it makes what I'm doing much more clear. Othertimes, I use the latter. It really depends on whether the two tests are related or not, as well as whether there are other things I want to do in the $var==1 case but only if $var2!=2.

So I often find myself writing a grep of a grep. Or a grep of a map of a map of a grep. Or a map of a grep of a grep. Or ... when a single map may just do fine.

Your first example, having two if's to check the same thing, isn't really analogous to combining grep's since each grep is checking different things.
