Hi,
Is there a reason why I cannot compile the following code:
module test;
struct Test {
int delegate(int) f;
}
Test s = Test((int x) { return x + 1; });
void main(string[] args) {
return;
}
dmd 2.057 says:
test.d(7): Error: non-constant expression cast(int
delegate(int))delegate pure
nothrow @safe int(int x)
{
return x + 1;
}
?
The 'this' pointer in the delegate:
Test((int x) { return x + 1; });
is a pointer to the struct literal, which isn't constant.
You actually want it to point to variable s.
The struct literal residing in static storage has a variable address?
Why would the context pointer point to the struct literal anyway? It is
not required.
OTOH if it were a function, it should work, but it currently doesn't.
It should even work for delegates. The context pointer would just be null.
