: It seems that the rand problem could be solved this way:

: my @nums = rand� (100 xx 100);
The rand function may be a bad example, since it's by nature a
generator, and you should maybe have to work harder to get a single
value out of it. We haven't really said what <$fh> xx 100 should do,
for instance. I guess the real question is whether xx supplies a
list context to its left argument (and whether rand pays attention
to list context). These might produce very different results:
@foo = (rand);
@bar = (+rand);
On the other hand, history has rand producing a scalar, so arguably we
should stick with that.
