Fine by me as long as it gets in.

Iḿ a bit curious, though. path2list currently returns an array of slices into
the original path. I have a hard time imagining memory allocation this way would
be much higher than as a range (unless the original path is also a lazy range). 

Next week finals will be over. Iĺl rewrite the bugger then.
