nimpy cannot be used in generic procs

[mratsim]

Due to limitation of the upstream semcheck and early symbol resolution, you cannot call a wrapped function in generic proc.

See https://forum.nim-lang.org/t/6321#38994

Ok, but the workaround is trivial, no? Just use nimpy.callMethod directly instead of the .() magic.

It's not in the README ;)

I don't think this particular problem should be in the readme. It's not a nimpy issue after all. Though it could be mentioned in callMethod documentation, which doesn't exist, PRs are welcome :)
