Co-existing Numeric and numpy?

Hi,

We have some older 3rd party packages that require Numeric (24.2), but like to also use newer
3rd party packages that require a recent numpy. Can Numeric and numpy co-exist in the same
process? -- I'm mainly worried about clashes at the C API level.

Thanks!

nope, there are no problems. In fact, converting between the two arrays 
types with asarray() works very efficiently.

I sure wish everyone would make the transition, though.

Thank you very much for the information!
There are weird but important reasons why we are stuck with Numeric 24.2 for the
foreseeable future. It is extremely valuable that you provide a smooth upgrade
path.
