As in, could you > encapsulate the GSL in this way? I doubt it. As do I now. After spending a little time playing with it, I discovered that it is very good at wrapping trivial things trivially. I took a simple GSL program I used to introduce students to GSL, that was a modified example from one of the GSL example files. Basically a little Hooke's law bit to use as input to an LU solver. Really short GSL program. What I discovered is that it doesn't take much to make this not work. :( Specifically passing arrays and vectors back and forth between C/Perl is hard (IMO). Since I don't do this on a regular basis, this isn't so bad. Also there is this PDL thing (http://search.cpan.org/~csoe/PDL-2.4.3/Basic/Pod/Impatient.pod) which doesn't look so bad, but it still doesn't solve the issues I want solved. >> Only when you have some ... odd ... structures or objects passing back >> and forth which require a bit more work. > > What's an odd structure?
