OK, but that limits you to the, um, 24 standard levels of precedence. What
do you do if you don't think that that's enough. Let's say you want to
define a "nand" operator:
my sub operator:nand ($a, $b) is inline { not ($a and $b) }
but you want nand to have a precedence lower than the existing 'and' but
higher than the existing 'or' (for some reason I can't imagine
offhand). It isn't like() anything, since there isn't anything currently
between 'and' and 'or'. Would that be something like:
my sub operator:nand ($a, $b) is below("and") is inline {not ($a and $b) }
