I was trying to mean that using something like :

class Small(IsRecord):
    field1 = defineType(CharType, 2, default="", position=1)
    field2 = defineType(Int32, 1, position=2)
    field3 = Float64

as as container for recarray metadata is definitely possible instead of the
tuple (formats="2aid",names=("field1","field2", "field3")), if using
Python2.2. IsRecord is a metaclass (introduced in Python 2.2) that allows
you to effectively separate the declared attributes from the implicit ones
in normal classes.

Of course, you can taylor IsRecord so as to fulfill your needs.

I hope that I have expressed myself more clearly now,
