Hello guys,

I have the following class...

class myclass
{
    private ubyte[] Array;
}

...and i want to create an instance of this class and access the array as
follows:

myclass mc = new myclass();
mc[0] = 100;

I was complety sure i saw this in the newsgroup but i can´t remember where
exactly.
How is this "thing" called?
In the .NET framework i see it in almost every library.

I hope you guys get the idea, please help.

	myclass mc = new myclass();
	mc[0] = 100;
	writefln( mc[0] );

Hahaha, cool man thanks, that´s exactly what i needed.

"Array Operator Overloading: Overloading Indexing" That´s the name for it. I´ve
learned something new today, thanks again.
