redefinition of symbol named '$< ... >'

A compiler error that took me a while to figure out. So happy to share how to solve this. Error:

./dainemo/utils/activations.mojo:0:0: error: redefinition of symbol named '$activations'
./dainemo/utils/activations.mojo:0:0: note: see current operation: 
"lit.file_module"() ({
^bb0:
}) {sym_name = "$activations"} : () -> ()
./dainemo/nn/activations.mojo:0:0: note: see existing symbol definition here

./dainemo/utils/activations.mojo:0:0: error: redefinition of symbol named '$activations'

"lit.file_module"() ({

./dainemo/nn/activations.mojo:0:0: note: see existing symbol definition here

Caused by empty files in a mojo module

mymodule/
    __init__.mojo
    activations.mojo --> empty file

mymodule/
    __init__.mojo
    activations.mojo --> empty file

Even if you delete the activations.mojo file now the compiler gets stuck in the same error. So you have to first clear the compiler cache: delete ~/.modular/.mojo_cache

Maybe it will be better to report this as a bug? Btw, same happened to me with cache not cleared, so definitely, there is a problem with that
