Guy who doesn't understand general statements and statistics: "Your title is wrong, _I have_ heard of that idiom".

A different guy with the same deficiency: "Wrong, it's a common idiom in (list of obscure languages)".

Plus: array slicing, in 95% of the languages mentioned (and 99% of common languages) is NOT what he talks about. It just returns a sub-array and it only takes an uper/lower bound.

Do you really think of Perl as an obscure language?

[batista]

Are 95% and 99% difficult to parse?

Plus, does "I've seen it in Perl" nullify the "an idiom you haven't seen" for the rest of millions of programmers that don't use Perl, or J, or ...?
