i like large files, it makes it so much easier to read the code, figure out what it does, find stuff, and refactor. i like it when the entire program is just one file, except for the modules source. i hate when there are 10000 files all containing 5-10 imports and then just one or two lines of logic. or worse; include files within include files several levels deep that all touch global variables. my idea of good abstractions is to only lift out code that has no couplings and no shared logic with the program, like modules that can be reused by other people in other programs.
