I sort of get it. But this part he writes in the discussion seems to hold, no? "What I mean here is that elixir has a predefined syntax. It has a number of predefined syntactic constructs, operators and function calls. And while I can with macros change the meaning of the constructs I cannot add new constructs or operators as the handling of macros is done after parsing. So if I want to add something completely new it ends up syntactically being a function call. Now elixir has many ways of disguising function calls at the end of the day they are syntactically still function calls. For example parentheses around arguments are optional, there is special syntax for property lists where the keys are all atoms, special syntax for using these property lists as function arguments, special handling of do ... end when it is a function argument, etc. Elixir's uniform abstract syntax makes it easier to work with these but I am still limited by only having the existing syntax."
