A common example of a programming "idiom" is the sequence

temp = var1;  var1 = var2;  var2 = temp;

for interchanging var1 and var2.  But the writer above is correct; this
isn't an "idiom" or even analogous to an idiom in the normal sense of
that word.  A better term might be "cliche."

I therefore propose that we discuss programming cliches...  :-)
