Whenever you care about performance, you'll quickly realize that
dynamic strings are plain inappropriate.
The concrete use of PShortString strings is inappropriate in your
sense, because it results in allocation, copy and deallocation of
temporary strings in the code, in many places. This behaviour gave
birth to my question.
Ansistrings result allocation copy and deallocation during *processing*.
The use of ansistrings would make the compiler at least twice as slow
and quadruple its memory consumption.
Also, don't forget that an AnsiString assignment, even when it doen not end up in memory
allocations, will execute two intelocked instructions in multithreaded process.
