Eh I think defmodule is fine here.
However the issue is that you cannot use bind_quoted in this way (I learned that well long ago). Basically what bind_quoted will do is turn the code into something like this from the return of your macro:
module_name = MySnippet
body =
(
def f(x), do: x
def g(x), do: x
)
defmodule(module_name) do
@doc false
defmacro(__using__(_opts)) do
quote do
body
end
end
end
And this is why you are getting the def is not allowed here message. I’ve always had to do ‘fun’ unquote messing when I had to do similar things. So if you Macro.escape the body in bind_quoted then use unquote(body) inside the function then it might work (you might need to ‘escape’ the inner quote though or something like that, I usually just don’t use bind_quoted at all in this case and just unquote through the layers as needed or build the AST manually without quote…).
