|Ah; I was confused by his notation; I didn't realize he meant the C \
|operator
|'->'.
Oh, i love this method-on-object as opposed to object-on-function
methodology.
while(_tr.read_line(*&_line) >= 0){
ln = _line.trim().squeeze().data();
len = _line.length();
which can easily exceed a 80x2[45] screen in C. Especially with
"more modern" frameworks which try to avoid namespace pollution
and easily exceed 20 bytes for a single function name alone.
Of course error handling is often a problem unless you go for
exceptions (terrible, especially if they do not have language
builtin support for file and line number, at least without
-DNDEBUG, imho), general state machines or whatever.
While at C++, the checked automatic upcasts are also very helpful,
especially if you have a deeper object hierarchy. (As in, struct
object{}, struct drawable{struct object super...}, struct
button{struct drawable super..}, then "drawable d;.. object*=&d
(or for heaven's sake &d.super) is much much better as
&d.super.super or even (object*)&d.)
Damn i have given up on perfection, and sometimes even on
"being explicit is better", but a shame it is.
Ciao, a nice Sunday and Good luck! from Germany,
