This would make Empty both a Module and not a Module.

  On top of that, it isn’t clear which instance of “a Drop post” is being replaced (though I think I can guess at which one).

[naught] the only one with a comma trailing it

[Axemabaro] Not exactly, the word either is ambiguous. Sometimes people mean it to be either X or Y but not both; other times you can remove the word either from the sentence and it has the same meaning. For instance I could write “you can use either a rag or a cloth to wipe the table” and in that instance a rag is both a rag and a cloth.

Smaller blocks might be useful, but it feels more intuitive to keep the keyword “Module” as only referring to built stuff.
