• match.call() equivalent?

  • substitute()

• It is tedious and error prone to have to do mental mapping from R language objects to the R6 classes. Provide both interfaces, e.g., For$ivar and For[[2]]

  • So [[, ... for the same code to work on R AST and rstatic objects, e.g. call[[1]] == call$fn
  • See rstatic_methods.R

• S4 as(, "character") and other methods should be present.

  • See rstatic_methods.R

• as() methods for going from R types to rstatic

• If not already done, make interface non-R6 and much more convenient. Instead of

  Call$new(Symbol$new("bob"), args = list(Integer$new(1), Numeric$new(10.3)))

  also have

   Call("bob", list(1, 10.3))
   Call("bob", , 1, 10.3)

  This is a little tricky as Call is defined and we need to invoke Call$new

  • Issue with overloading Call, Integer, ... as regular functions as then can't see the Call R6 object. Want to avoid Call$new() but instead use Call() function directly.

• How well has R6 served you? What about reference classes? S4?
