Hello,

I get the following error when I evaluate `using MyModule` via Atom - Juno. Somehow I don’t get this error when I evaluate it via julia.exe or VsCode. I make the module available via `push!(LOAD\_PATH, \<mymodule\_path\>). I already tried to delete the MyModule.ji in .julia/compiled folder, but it doesn’t work

Does somebody know what could be the reason for this ?
