Hi Sandro,

no I can't. I was just rephrasing what I read in some sources online
and asking here for educated opinions on if this interpretation is
right or wrong. Thanks for taking the time to "debunk" some of the
myths floating around.

Do you see it the same way in regards to the usage of templates in C++
libraries licensed under the LGPL? Is this also a "non-issue" in the
end?
