I have been agreeing (with Spencer, IIUC) on this for a long
time (~ 3 yrs, or more?), namely that I've come to see it as a
"design bug" that rpois() {and similar} must return return typeof() "integer".
More strongly, I'm actually pretty convinced they should return
(integer-valued) double instead of NA_integer_ and for that
reason should always return double:
Even if we have (hopefully) a native 64bit integer in R,
2^64 is still teeny tiny compared .Machine$double.max
(and then maybe we'd have .Machine$longdouble.max which would
be considerably larger than double.max unless on Windows, where
the wise men at Microsoft decided to keep their workload simple
by defining "long double := double" - as 'long double'
unfortunately is not well defined by C standards)

Martin if you are in favor, then certainly no objection from me! ;-)
So now what about other discrete distributions e.g. could a similar
enhancement apply here?
