I did not even think to extend it that way! What a cool suggestion. Right now I 
am working on a macro as defined here, since there are times it makes sense to 
list dependencies explicitly https://github.com/zyrolasting/kinda-ferpy/issues/2

Now if I could get a #-notation to support explicit dependencies without 
sacrificing too much readability, I'd probably prefer it over all other 
variants.
