Lists?

[leikind]

This hack is so cool :-)

I assume, it is not possible to match empty lists and heads/tails?

my_length([], Acc) -> Acc;
my_length([_|T], Acc) -> my_length(T, Acc + 1).

my_length(List) -> my_length(List, 0).

:-) Thanks! There's no support for lists yet but no reason it couldn't be added. I thought about doing it but had to get the proof of concept done in time for a talk I was giving.

Feel free to open a pull request if you'd like to have a go! If not I might get around to it myself eventually...

Writing this thing should be fun :-) Please don't take my question as a feature request, I was just curious.

Don't worry! I wouldn't expect anyone to actually use this gem, in fact I would strongly advise against it! It's a bit of fun. But yes, list support would be a cool addition!
