Hi!
It looks like PEP 498 (f-strings) is going to be accepted soon. Anyone
interested in implementing it for Cython?

It's certainly a bit of work, but it's also very much Python-level
functionality and most of it can be handled in the parser, so I would

Hello Cython-devel,
I noticed that now unsigned constants like
DEF foo = 1
become 1U in the C source code.

Was this change of 1 to 1U in

running "python setup.py install" gives me
