Compiler behaves differently for different cases when handling field
initializers for structs:

struct S1
{
    int a, b, c;

    static immutable S1 C1 = { 1 2 3 }; // no commas here, compiles
    static immutable S1 C2 = { 1, 2, 3 }; // compiles as well
}

int foo() { return 3; }

struct S2
{
    int a, b, c;

    static immutable S2 C1 = { foo() 2 3 }; // compiles (and works)
    static immutable S2 C2 = { foo() 2, 3 }; // compiles (and works)
    static immutable S2 C3 = { 2 foo() 3 }; // does not compile: comma expected
separating field initializers
}

Encountered this on 2.048 Windows (AMD64), 2.047 and 2.048 Linux (AMD64)
