@Dennis for the previous version, it would have required parentheses. !~T is genius though, thanks!

I got that the T^ part, but somehow missed that lc changed the case of $'. Prepending lc to $' would have been slightly shorter. That should still work for either approach: lc$'!~(T^lc$_%2) or ($_%2x9^lc$')!~T

@Dennis TT^01 → de, which would fail to work correctly if a range were suffixed with EVEN or ODD.

Man, this is clever! Unless I'm missing something, you should be able to eliminate lc=~.

@Dennis I was surprised myself when reading perlrun that "-F implicitly sets both -a and -n." I think it's best to add -a in this case, if it only works for 5.20 onwards.

| Jun 3, 2015 at 17:16 | comment | added | Dennis | In case anybody else is having trouble: This seems to require a specific version of Perl. It works fine with 5.20, but prints nothing with 5.18. | |

* is one character shorter than &&, making for an easy improvement: $\+=/\d+ ?-/*($'-$&>>/o|e/i)+1for@F}{

how does this work for pg. 20: 13-15 even? or pg. 20: 13-14 even?
