I tried creating UDL strings like you suggested (but with a space
between the literal & s), but it doesn't compile for me.

A simple program like:
const unordered_set<string> myset ({ "a" s, "b" s, "c" s, });
int main()
  cout << "size of myset = " << myset.size() << endl;

Doesn't compile, I get the error:
error: expected ā€˜}ā€™ before ā€˜sā€™
    7 | const unordered_set<string> myset ({ "a" s, "b" s, "c" s, });

Maybe I'm doing it wrong (I haven't used UDLs before).
