Examples of ArgumentIterator

org.renjin.invoke.codegen.ArgumentIterator
Iterates over an argument list, nesting into ... as necessary.
For example:
f<-function(...) pow(..., 2) f(8)
When pow(...,2) is reached, the symbol '...` (Symbol.ELIPSES) must be evaluated and merged into the list of arguments.
