Built-in expanders crash when used as identifier macros. #179

Closed Idorobots closed 1 week ago

Each expander should handle that case explicitly.

This happens due to the assumption that these are used as applications:

(let ((node (ast-list-car expr)))
      (raise-compilation-error
       node
       "Bad `define` syntax, expected either an identifier and an expression or a function signature and a body to follow:"))
