Re: (b)make: selecting every other element from a list

Any particular reason for using := and not = in this place?

Oops. I was sure this didn't work in older (NetBSD 4.0.1) versions of (b)make, 
but I just checked it does work. I (wrongly) remembered this ending up in l2 
being ${_i} ${_i} ${_i} after the loop, and subsequent expansion of ${l2} 
repeating the last value ${_i} was set to. Strange.
