Fixed, the former is correct, the latter I think is a bashism that may not work. Unfortunately I plucked that from a project in a very broken state. > I can't see how your example relates to static or dynamic typing, though. Because with static typing you know the object/file graph at compile time and only affected tests need to be run. In that example the .test files will only be built when their dependencies change and .testresult will only be created if .test is built, everything is incremental and "make test" won't execute any tests if there are no changes that could affect them.
