[erlang-questions] Parse-transforming !! to a function call

[Christian S]

It doesnt even parse, so the parse-transform cant work on it.

{ok, Tokens, Lines} =  erl_scan:string("foo(X) -> foo !! X.").
erl_parse:parse_form(Tokens).


It has been suggested before that the backtick or similar could be used
to create an infix operator out of an arity-two function, like in haskell.

X `add` Y vs add(X, Y)

or in your case

x `!!` y instead of '!!'(x, y)

I'm not all that crazy about the idea though. LispErlang would be cooler. :)
