I always used to use compound literals for this purpose:

     t.emplace_back( (Trivial){1,2.0,"blah"} );

Strictly speaking I think these compound literals are only a feature
of C, but every C++ compiler supports them.

Ville posted "C++20 allows initializing aggregates with the
parenthesized syntax", so does that mean we pretty much have compound
literals in C++ except that we use the following syntax?
