Yes, it's arbitrary R code that is evaluated, so paste0() would work.
You're right that it's a big door and could let people do weird
things. Do you foresee a problem with that?
I guess one could have implemented NAMESPACE parsing by evaluating the
code in an environment (inheriting from the base namespace) where
import(), export(), etc, were defined. Maybe there's a good reason why
it was not implemented that way.
