I’m looking for a hypothetical @istoplevel, presumably a macro, which could work like this: module Foo @istoplevel() # true end julia> @istoplevel() # true function foo() @istoplevel() # false end Does anything like this exist or can it be constructed?

Is there a way to determine whether code is toplevel?

Yes, you can set a gensym variable and test if it is indeed set on __module__.

Should macros get an `__istoplevel__` or `__scope__` argument?
