For me "clean" sounds not the same as "remove" (I used to the thought that
remove means to remove object from larger object, and clean is clean the
object internally (remove its content?), but it continues to exist and all
its relations with parents are not touched), but I'm really far from being
an expert in English.

hm, looks a bit strange to add test first and then fix bug, but on the
other hand it's more demonstrative, OK for me.
