1st of all thanks for the helpful replies.
Indeed, Pyrex compatibility is a requirement for me. I want to use/test
the Cython-generated code but need to be able to revert to Pyrex in case
of problems. Anyway, what I have done is
def foo(bytes bar=bytes("")):
c_foo(bar)
This compiles and works under both Cython and Pyrex, so for the sake of
compatibility, this seems to be the way to go for the time being.
But doesn't the explicit conversion seem pretty redundant/ugly?
Cheers,
Joachim
