[myhdl-list] intbv return types

[Christopher L. F. <chr...@gm...>]

Curiosity, what was the rational behind the mathematical operators for 
the intbv object returning the integer values and the logic operators 
(shifts, and, or, xor, etc) returning an intbv object?

Example
a = intbv(1)
b = intbv(2)

c = a + b
type(c)
<type 'int'>

c = a ^ b
type(c)
<class 'myhdl._intbv.intbv'>

Thanks
Chris
