This came up in the long past. On reading the LGPL, you are correct that
the text AND FSF's definition of 'derived' means if you use the class,
it must be
LGPL also. However, I think my obstinance on the matter got FSF to publish
Given what is said there, "work based on" in the LGPL cannot mean the
as that phrase used in the GPL, but for some reason, this oversight
doesn't seem to
bother too many people.
