[Bioc-devel] when to use combine() vs c()?

We clearly need c() for GRanges since I believe there is tons of code
for that.  My guess is that combine() is much less used.

I don't know what combine does for GRanges, but in general I would not
expect c() and combine() to necessarily do the same thing.  c() I
think of as putting the objects after each other and I think of
combine as putting the objects next to each other (essentially combine
two different sets of samples - which of course does not make a whole
lot of sense for GRanges).  I also think that too few people know of
combine(), but I always define methods for it in my packages, allowing
me to put objects next to each other.

Specifically, for GRanges, I would not expect that the two GRanges I
combine would contain the same elementMetadata and I would expect that
combine would fill them up with NAs as appropriate.  Not so sure
whether that is useful.
