Suppose we do this:

e <- f(a = 1, b = 2)
ls(e, all = TRUE)
[1] "..."

[1] "..."
Is there any way of getting a and b given e without
modifying f?
evalq(list(...),e)
$a
[1] 1
$b
[1] 2
I'm wondering though whether we should allow the internal DOTSXP value
of "..." to escape to the user level. Might be more appropriate for
get(e,"..."), e$... (and as.list.environment and maybe a few other
things) to give the "Error: '...' used in an incorrect context" error
if the value is a DOTSXP.
