Re^2: new DLL compile code inside script languages

It could be even faster and shorter...

sub suma {
    my $n = shift;
    return $n * ($n+1) / 2;
}

Listen roboticus, we are comparing brute-force approaches here...	[reply]

Jorge de Burgos: True ... but I was just trying to illustrate that it's often the case that looking for a better algorithm is more productive than optimizing the current code. ...roboticus	[reply]

But that's not a very good thing to compare. What does it tell you? That C is faster than Perl for a very specific case of tight loops and integer arithmetic that is rendered totally moot by the existence of a trivial O(1) algorithm. What it doesn't tell you is whether Perl, Inline::C, PDL, or this VB-inspired DLL is a good choice for any real-world problem. It does not implement an interesting algorithm, so you can't compare which provides the most readable implementation; and it does not benchmark an interesting calculation, so you can't really compare performance either.
