Thanks for pointing out the advantages. I can see the point, but can't
help to think that I'll be reading code like this soon:
s := '(' + x.ToString + ', ' + y.ToString + ')';
Instead of
s := Format('(%d, %d)', [x, y]);
What I'm trying to say with this (admittedly contrived) example is that
when you are forced to read the docs to find out which functions you can
use for converting numbers to strings, you'll probably discover
functions like Format. At least in my case, the most useful tricks I
learn come from reading the documentation for something, then exploring
a bit.
I apologise if I come across as overly cynical and I do appreciate
Sven's work in the compiler!
