Well, we have complex dialogs too for example. They should avoid to need
seconds more to load on a not-so-fast computer.
(Also performance can be important if the computer is a server handling

Keeping the interface simple means that you can have less surprises. Let
QString do what it can do well and put in the special class only what is
needed for a correct translation.
Especially that I suppose that numbers do not need really a special handling
for scripting. (Somebody wanting to replace (European) Arabic digits by
Indian-Arabic digits would probably want to convert all occurences of
numbers, be they in strings, 32 bit ints, 64 bit ints, floats, doubles, long
doubles or whatever variable type that can hold a number.)
Have a nice day!
