[erlang-questions] beta release of merl - metaprogramming in Erlang
Tue Feb 4 15:38:39 CET 2014
It also have some caveats, if we really want to make use of it:
- I don’t have an idea of an obvious syntax for extracting the attributes
- I need multiple escape operators to do stuff like case E of ``Clauses end
- I need to abuse yecc to be able to do <|form| SomeForm |>
Glad you find it interesting though!

I had long considered doing something Meta-ML-like for Erlang, but wanted to start with something simple that didn't need a modified parser (not even macros or transforms at the simplest level), and then work my way up. The advantage is that it works today, without forking OTP or pushing an EEP to add metasyntax to R18. :-)
