(strange that it is called eval-defun but it actually evaluates the top-level sexp, even if it is not defun) i don't know how else should have i indicated, that all the code bellow needs lexical binding. is there a way to do that without confusing anybody, so that it does not look like it doesn't do what the author thinks it does?
