yet another sort issueby mce (Curate)

mce has asked for the wisdom of the Perl Monks concerning the following question:
There are many posts about the magic of sort.
I have a question that -I think- isn't handled before.
Last week, I found that the result of my code was not correct, and after digging deep in my code, I found that the problem was a typo, as I have written cmp instead of <=>.
This bug is one of the hardest to find as the perl code runs OK.
Now, when warnings are on, perl complains that the following code is wrong.
but this isn't.
Wouldn't it be possible to alter perl so that it complains when using cmp when comparing only numbers?
At least, I would think this is very usefull.
I don't know that much about the perl internals, but I guess it must be doable.
