I wrote about _logical_ separation.  Oberon puts module in a single
files, IIRC declarations of exporeded things just have stars before.
So the is only tiny overhead in terms of extra charaters, but logical
separation is there.

In other words, you only support modularization at library level,
more or less what C is doing (using either compiler extentions or
external tools one can control what is exported from shared libraries
build from C files).
