The package

package variadic

+1 This is definitely a very required feature. Or the possibility to pass a list or a dictionary as argument. Thanks a lot for gopy, it is the missing link for golang adoption by pythonistas!

[rcoreilly]

still not supported!

[piaoxue1949]

still not supported!

Any news on that? Would be great to have this feature!

My PR#279 should address this.
