I wasn't aware of lwarn, so I checked it's doc string and found a
really minor error: the first period in the description of the
TYPE argument should either be deleted or replaced by a comma:

,----[ C-h f lwarn RET ]
| lwarn is an autoloaded Lisp function in `warnings'.
| (lwarn TYPE LEVEL MESSAGE &rest ARGS)
|
| Display a warning message made from (format MESSAGE ARGS...).
| Aside from generating the message with `format',
| this is equivalent to `display-warning'.
|
| TYPE is the warning type: either a custom group name (a symbol).
| or a list of symbols whose first element is a custom group name.
| (The rest of the symbols represent subcategories and
| can be whatever you like.)
|
| LEVEL should be either :debug, :warning, :error, or :emergency
| (but see `warning-minimum-level' and `warning-minimum-log-level').
|
| :emergency -- a problem that will seriously impair Emacs operation soon
|             if you do not attend to it promptly.
| :error     -- invalid data or circumstances.
| :warning   -- suspicious data or circumstances.
| :debug     -- info for debugging only.
