Well, the reason why we recommend to non-experts to not use function calls
inside gettext() _is_ that xgettext then cannot determine the possible
set of strings that can be the argument of gettext() and put this set
into the POT file. There is no other reason. If you are expert enough
to ensure that all possible strings appear in the POT file, you can
use function calls as argument.

Thanks Clytie for the forward.
