Is there any way to custom __ENV__
?
For example, how to make __ENV__.file
return “I need a custom value” when I execute it within a file named “a.ex”.
Thank you

An instance of Macro.Env must not be modified by hand.
But on the very same page there are some hints on how to get modified environments.
Thank you.
But I didn’t use it for Code.eval_quoted
.
Finally I do this by edit the AST.
