`eval` in macro can easily evaluate in the wrong scope. It is totally OK if the intended sematic is to evaluate the part of the expression only in top-level (global) scope, which includes macros that should only be used in global scope, like `@enum`. You should also make sure the eval is done in the right module (`current_module()` pre-0.7 and ` __module__ ` post-0.7).
