Left arrow

[mlajtos]

R uses left arrow as an assignment. E.g.:

sumofsquares <- function(x){
  y <- x^2  
  return(sum(y))
}

Also, APL uses RTL flow. So maybe supporting "<-" wouldn't be such a bad idea..?

Combining the two in the same chain would be chaotic, for sure. But using one for (LTR) node composition and the other one (RTL) for applying it and getting some result, might be okay. Example:

BB:{In -> Transformation -> Out}
result <- BB <- in

Looks weird at the first glance, but in a strange way it makes total sense.
