Or rather "make myfile.o && make" if you want to rebuild the module. The
trouble I find is that often I either don't expect the compilation to fail
(since my edits are always perfect ;) ) or I just don't think to check the
changed file first, so I just type "make". Auto-generation of the
compilation order would cater automatically for these thoughtless moments
and actually save a significant amount of time (for me, at least).
