fwiw, that's what I use to convert a function to a delegate (not my
invention):
R delegate(T) toDg(R, T...)(R function(T) fp)
{
struct dg
{
R opCall(T t)
{
return (cast(R function(T)) this) (t);
}
}
R delegate(T) t;
t.ptr = fp;
t.funcptr = &dg.opCall;
return t;
}
Note that this won't work for ref arguments.
