If I meant to write 1,2,4 but typo'd the "4" and wrote 1,2,3, then I would like to know about the typo. Having 1,2,4...* not work will help with that, but my experience is that people will expect 1,2,4...* to work because it will seem obvious while they are writing it (and I just typed "1,2,3" and had to delete the 3 and type 4).

I figured there would be an exception for simple counting lists so that just "2 ... *" would be sufficient for "2,3,4,5 ... *". So 1,1...* vs 1.1...* would be another ugly typo that I would like detected. 100,101...* vs 100_101...*?

So I respectfully disagree. But I figured it would be an up-hill fight against the common Perl mindset of making things rediculously terse.
