Yes and should I know what spirit::parse do if some exception is thrown
inside? Maby it returns empty vector, whatever? Is it aware that some of
the exceptions are ok? I don't know it and I do not want to know it.
From the previous example. If you know that you need only 4 elements
and you use std::vector since there is no static_vector yet, must you
parse all of the elements? You'll probably provide some wrapper/adaptor.
This adaptor will probably work with std::vector and static_vector as
well. Not to mention all other containers that has push_back().
This usage is some special case. Of course, you'll find some number of
those but in general this way of thinking will be wrong.
