Does anyone know the historical roots of "n" and "m" for "min" and
"max" in the regex quantifiers?  I can never get a mnemonic for which
is which.  (Of course, the min is to the left of the max.)  Perhaps if
I know it's roots, I'll remember.

That is (n,m) = (0,7) in this snippet:

    if ($fruit =~ /b(an){0,7}a/) {
        print "You've got an modular banana\n";
    }
