Yup: macro-expansion of `(test-def (A B C))` evaluates the body of `test-def` and hence calls `test-fun`, but since this is done during compilation, `test-fun` needs to be not just compiled but also defined. > I tried to use eval-and-compile in this case but the problem is that in > my real code test-fun calls another function (a minor mode) that needs > to be defined later (in the same file); It's hard to imagine a macro which needs to enable a minor mode during its expansion. Are you sure? Stefan
