Support for piping the first argument of R functions

**Is your feature request related to a problem? Please describe.**
A key part of tidy workflows in R is using the %>% operator to pipe the first argument to a function. This is the opposite of F# piping, which works on the last argument.

**Describe the solution you'd like**
For typed arguments, one solution would be to generate an additional overload for each R function that took a piped value as inserted behind the scenes as the first parameter to R, then only exposed the rest of the arguments to the user.

**Describe alternatives you've considered**
It is possible to make an operator to pipe through a specific named parameter when using the [ string * obj ] overload of an R function, but this is not ideal because for example in dplyr it means hard-coding _data as the item to be passed.
