Re: Re: DWIM on sub input

A few explanations:

I split to 4 elements because of the case "1,2,3,4,5,6,7". I want to discard the extra elements.
Good catch on the upper bound. Thanks!
Yes, I do want to allow 40.3 and 0.01 and the like.
I don't want to re-use @_ because of the ... (which are the extra parameters that aren't germane to the discussion). In part, I'm still working the API so I may allow for craziness within @_.
The reason for the substitution instead of int is that int throws a warning. Plus, int('a1') != int('1a'), whereas my code will treat them the as the same.

Split to 3 elements, because you only want to keep 3. You would have caught `(1, 2, 3, 4)` from `"1,2,3,4,5,6,7"`. D'oh! I was wrong. But `"4,5,6,7" == 4` ;) -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l] [select]
