However, I came across one thing in solution #3 that I posted yesterday.
$pair.fmt("%s %s") is nice, but it doesnt allow for any action on either
value or key before printing (I wanted to print the value as a
percentage), and this had to be done in a printf statement. In fact the
printf statement was the longest and ugliest statement in the program.
Maybe I'm missing something, but you can always do:
$pair.key.foo.fmt("%s"),
$pair.value.bar.fmt("%s")
Larry
This surely requires that foo and bar are defined as sub's.
Suppose I just need a single transformation of a value before outputting
it? Eg., expressing .value as a percentage of $count?
Is there some way to include a one-off in the subroutine "chain"?
Something like
$pair.value.{shift / 10}.fmt("%s");
