Problem solved. Why write 6 lines when 3 will do?
Just because I'm a simple man. :)
I usually program mostly in C and when in D, I go in the same way
but using features like: GC, strings, AA etc.
Of course your version is a D'ish way of handling things, and I
can't contest it looks better visually. But if size was problem I
could have written:
void main(){
string s, str = "4A0B1de!2C9~6";
foreach(i;str){
(i >= '0' && i <= '9') ? s~=i : null;
}
writeln(s);
}
Well still 1 line off, but I goes with my flow. I mean this
example is a simple one, but usually I can see and understand
what a code in C is doing (more) easily than D just looking at
it. Don't even ask about C++, because I gave up. :)

PS: I spotted something on your code, you're converting the
result to int, this can lead to a overflow depending the values
in the string.
