How to handle sequences?

[andreaferretti]

If I understand correctly, seqs should be supported. Anyway, I tried this example

proc sum*(xs: seq[int]): int {.exportpy.} = 0

and it fails with

stack trace: (most recent call last)

I tried with various nim versions, from 0.13 to devel

Can I ping you on this? I am interested in Nim-pymod, and any information (even - it doesn't work anymore and we are not interested in keep developing it) would be interesting.

If you know any combination of Nim/Python versions that should work, I can use nim-vm and virtualenv to try it out

@jboy Hi, can I ping you? Even if the library is not developed anymore, any information (what remains to be done, how it works so that other people can hack on it...) would be useful!
