Hi.
Just out of curiosity, what are the evils of AST macros (or
could you point me to something you like on the topic)?
There was extended discussion in old threads but short summary of
my opinion is:
- allows implicit changes to language semantics (== learning new
framework is effectively learning new language)
- overlaps in functionality with mixins for majority of use cases
- less intuitive to newcomers (though cleaner/safer to
experienced programmers, I admit that)
- requires standard (and stable!) AST format
