Sounds hard. I doubt there is enough commonality with the numarray to
make bolting on the pure-Python RecArray and CharArray implementations
reasonable. RecArray and CharArray are very much dependent on
generic.NDArray; I doubt they're easy to port to Numeric.

I don't think so.

No.
Sorry about the slow response,
