Hi,

The code below fails with "Error: delegate 
`onlineapp.A!int.A.__dgliteral2` cannot be struct members":

T f(T)(lazy T value) { return value; }

struct A(T) {
     immutable a = f("hi");
}

void main() {
     A!int i;
}

Removing the lazy keyword fixes the error. But I'm wondering if I 
can keep lazy there. Is this a compile bug perhaps?

The actual use case where this is causing a problem is from this 
function:

https://github.com/aliak00/ddash/blob/5c9f2923028c7c16b89b041b399f6fb1bc73639c/range/source/ddash/range/front.d#L25

and needing to use it in a declaration scope of a struct in this 
kind of way:

struct A(string name) {
   immutable firstPart = name.split("|").frontOr("");
}

Cheers,
