Any chance we could get a existance operator and a pipe operator

Really cool language, I really enjoy writing it... that being said, I would absolutely love to see a nil check/existence operator (maybe ?) and a pipe operator (similar to Elixir |>). If the work was done, is this project open to any feature additions?

YueScript extends MoonScript with support for both of these, among other things. It seems to borrow from LiveScript.
