R devel - Apr 2017 - Problems with S4 methods dispatching on `...` (aka dotsMethods)

Hi all,

I recently encountered some unexpected behavior with S4 generics
dispatching on `...`, which I described in
http://stackoverflow.com/questions/43499203/use-callnextmethod-with-dotsmethods

TL;DR: `callNextMethod()` doesn't work in methods dispatching on `...`, and
arguments of such methods are resolved differently than the arguments of
methods dispatching on formal arguments.

Could this indicate a potential problem with the implementation of the
`...` dispatch?

Cheers,
Andrzej

Thanks for pointing out these issues. I have a fix that I will commit soon.

Btw, I would never have seen the post on Stack Overflow. It's best to
report bugs on the bugzilla.

Great, thanks Michael for you quick response!

I started off with a question on SO because I was not sure whether this was
an actual bug or I was just missing something obvious. I'm looking forward
to the patch.

Cheers,
Andrzej
