avoid paying the price of constructing a QStringList if they are unused.
That's what I was wondering about: constructing a QStringList is just a copy
of a pointer, and while not totally free, it is next to nothing compared to
the additional heap allocation of a new'ed QStringList...
It's still a good enough trade-off, considering we'd need to keep a bool
elsewhere.
(we need std::optional :)
Aye.
What speaks against shipping a copy of std(::experimental)::optional and
using that one when the configure script notices std::optional not being
available yet? How about letting qmake picking the right std::optional
when configuring a project?
Ciao,
