Triggers

[Sjoerd van Leent]

OK, to make matters worse.

As I was reading so many things about properties, keywords and a bunch of other 
interesting things, perhaps triggers.

Triggers are, in my opinion, functions that act as delegates, and are called 
before or after one or more other functions. Maybe we can do something with 
this? It would introduce some aspect programming to D.

file 1:

class Foo
{
    int mybar;
    int myother;

    void bar(int i)
    {
        mybar = i;
    }


    void other(int i)
    {
        myother = i;
    }
}


file 2:

trigger(before) : "*.void * (int *)"
{
    writefln("calling ", this.currentFunctionName);
}

trigger(after) : "*.void * (int *)"
{
    writefln("called ", this.currentFunctionName);
}


This might be something for D3 though...
