sometimes I want to compile and not save files nor be asked

sometimes I want to compile and not save files nor be asked

Compile's docstring should mention compilation-ask-about-save.

Documentation:
*Non-nil means C-x c asks which buffers to save before compiling.
Otherwise, it saves all modified buffers without asking.

Well gosh, how about what if we just plain don't want to be asked
about saving, and don't want gratuitous saving?

I suppose that 3rd possibility will not fit into the nil/non-nil
paradigm mapped out above, that leaves no room for adding more
possibilities later.

I'm not sure about that: there are 7 compilation- user options, of which
only compilation-read-command is mentioned in compile's doc string.

Good idea:

We could use your changes if you could get the necessary legal papers
to cover them.  However, we don't have them, and the result is that we
cannot implement changes the way you have written them.  It actually
makes our work harder when you post changes, because then we would
have to make sure not to implement the change the way you wrote it.
