No, sometimes I want i to be the value it has at the time the
delegate was defined. My actual usecase was more like this:
void delegate()[3] dgs;
for(int i = 0; i < 3; ++i)
dgs[i] = (){writefln("%s", i); };
And I want three different delegates, not three times the same.
I tried the following:
void delegate()[3] dgs;
for(int i = 0; i < 3; ++i)
{
int j = i;
dgs[i] = (){writefln("%s", j); };
}
I thought that 'j' should be considered a new variable each
time around, but sadly it doesn't work.
Maybe std.functional.partial can help you.
