Yes, I think so. Why not .type for Python types (and numarray
compatibility) and .typecode for C types (and Numeric compatibility)?.
numarray supports both right now without problems.

Besides, in numarray.records module, you may find the following map:

numfmt = {'i1':num.Int8,  'u1':num.UInt8,
          'i2':num.Int16, 'u2':num.UInt16,
          'i4':num.Int32, 'u4':num.UInt32,
          'i8':num.Int64, 'u8':num.UInt64,
          'f4':num.Float32, 'f8':num.Float64,
          'c8':num.Complex32, 'c16':num.Complex64,
          'b1':num.Bool}

which I find very useful and intuitive, but I guess it is incompatible
with current Numeric convention (that I find quite confusing, anyway).

Cheers,
