is it possible to temporarily change the destination environment where
objects are written to?  I am thinking

  a <- new.env()
  attach(a)
  ### run some code, such as...
  b <- function(x) x
  detach(a)
  a$b

obviously, this is wrong.  attach() only attaches for read access.  I could
copy the globalenv, run my code, see what objects have been changed (how?),
move the changed and new functions into my a environment, and then restore
globalenv.  or is this already done somewhere else?
