In an old FWP post I found online, there is a golfing construct I
can't figure out; this is all the post says
\$h{X} is one less than ++$h{X}
If it weren't for the leading backslash, the interpretation of "one
less" would be obvious and hardly worth remarking upon in such a
post. But given the leading backslash, I figure that the "one
less" is referring to "one fewer characters". Still, I can't figure
out what the whole thing means. Any help would be much appreciated.
TIA!
