That's an interestng idea. I think it could be done fairly easily by having 
Drake invoke the delegates indirectly like this:

Target t; // global
void invokeBuildStep(Target currTarget, {type} dg)
{
    t = currTarget;
    dg();
    t = null;
}

Only thing though, is if there's any special members added to the Target 
subclass being used, the user would have to cast 't' to access them. Then 
again, that's an issue in the current design, too. I'll have to think about 
this...
