How can I dump the elements of a list into the global enviornment (or equivalently a function's enviornment)?

I've got a list that I have saved. I want to load the list, and then have all of its elements transferred to the global environment. Or, equivalently, to a function's environment if the object is loaded inside a function.

Here is a simple example. How can I automate the last few lines?

L <- list(goats = 'goats', cheese = 'cheese'
, numbarz = 1:5, nice.model = lm(rnorm(100)~rexp(100)))
save(L, 'L.Rda')
rm(L)
load('L.Rda')
goats <- L$goats
cheese <- L$cheese
numbarz <- L$numbarz
nice.model <- L$nice.model

See `?list2env`. – lmo Mar 07 '17 at 19:41
Yeah `list2env` sounds like what you want. But as always in these cases I have to ask why do you want to do this? – Dason Mar 07 '17 at 19:46
`list2env(L, .GlobalEnv)` !! Want some points? Make it an answer – generic_user Mar 07 '17 at 19:46
@Dason I'm working on a paper where some bootstrapping routines take a long time. I want to save the results when done, then comment-out the lines that run them and then load them later. It is much less cluttery if I save the results as a list. – generic_user Mar 07 '17 at 19:47
It's not like this is production code or anything – generic_user Mar 07 '17 at 19:48
