the following code seem problematic to compile...

====
import std.algorithm;
private alias void delegate(int, int) SlotDelegate;

class A
{
   void DIT(int a, int b)
   {
   }
}

int main(string[] argv)
{
   A a;
   SlotDelegate x= &a.DIT;

   SlotDelegate[] _slotDg;
   _slotDg.remove(x);

   return 0;
}
====
I have some strange error:
Error: incompatible types for ((pos) < (from)): 'uint' and 'void delegate(int, int)' C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d    5609


I try a method like that as well (but similar problem! :( )
====
void removeAt(T)(ref T[] array, int index)
{
   if(index < 0 || index >= array.length)
       return;
   const T[] empty = null;
   array.replaceInPlace(index, index + 1, empty);
}
==== 

Remove takes an offset, not a value as far as I know.

If you need fast lookup and removal you could use hashes instead:

int main(string[] argv)
{
    auto a = new A;
    SlotDelegate x = &a.DIT;

    bool[SlotDelegate] _slotDg;
    _slotDg.remove(x);

    return 0;
}

Seems like gmail likes to cut my code. If that didn't paste well here: http://codepad.org/cyEDHSGc

There is a remove() method in std.algorithm!I even got asked why I was reimplementing it!
(well, because I didn't know it existed hey!)

works fine with, say, int...

but not with delegate!

associative array will solve the problem indeed.. (I hope) but they use way more memory!
it would be nice to have remove working() :)


Further, as you can see in my post, even my (reasonable) implementation of removeAt() fail! :(
(but, again, it works for int!)
