There's no hurry: this is a mailing-list, not an IRC channel.

current-load-list is an internal undocumented variable.
I'd stay far away from it if I were you. I can't think of any case
where it can give you better info than `load-file-name'.

This example seems to fail the "those cases do show up" test. Not just
because the requires/loads tend to occur early in an Elisp buffer, but
also because a call to `find-file' (or set-buffer for that matter) at
the top-level of an Elisp buffer is extremely rare and strongly
discouraged by the convention that loading an Elisp file should not have
any "visible effect" (this convention is useful/necessary to allow
things like Customize to load files at will, e.g. just to get the needed
info to build a customization buffer).
