I can partially solve this with do.call, but there is another problem. Quoted
expressions are evaluated during the assignment:
te <- new.env()
> tq <- quote(print("!!!!"))
> do.call("$<-", list(te, "aa", tq))
[1] "!!!!"
This is some weird do.call and $<- interaction. Does not happen with other
functions.
