numbuf =3D data[2:30:4][1]

in order to get a copy (in a new memory location) of the memory buffer = in the selected slice to work with it. Would that be interesting to implement?.

It's an interesting idea, but I think it's getting somewhat beyond the scope of Pyrex. I don't think I'll be trying to implement anything like that in the foreseeable future. The Pyrex compiler is complicated enough already, and I don't want to add anything more that isn't really necessary.

Is (or will be) there any way in Pyrex to automagically create diferent flavors of this function to deal with different datatypes?

Same here, and even more so -- I'm *definitely* not going to re-implement C++ templates! :-) Greg Ewing, Computer Science Dept, +-------------------------------------= -+ University of Canterbury,=09 | A citizen of NewZealandCorp, a=09 | Christchurch, New Zealand=09 | wholly-owned subsidiary of USA Inc. | greg@cosc.canterbury.ac.nz=09 +--------------------------------------+ ------------------------------------------------------- --=20 Francesc Alted
