the *why* (I'm sure someone on the list smarter than I can
: answer), but it
works if you change it to:
:
: my $n = INT_MAX() - 1000;
Simply because Perl handles constants like
built-in functions. When you say "INT_MAX - 1000", that's equivalent to
"INT_MAX(-1000)". Since INT_MAX is a constant function, you just get the max
again.
