           Summary: Weird constructor syntax failure
           Product: D

          Severity: normal
          Priority: P2

After adding a constructor to a struct in my code, I noticed my {} initializers were no longer compiling, with a suggestion by the compiler to use ( and ) instead.

Understanding this probably means to use the full constructor prototype, not just just replace { with (, I decided to just mass replace the { and ( anyway.

The resulting error was actually incredibly strange, and I can't understand the behavior of DMD in this instance, and therefore assume it is a bug.

Example:

struct Foo {
    float a, b;
}

void main() {
    Foo[] xs = [(0, 1), (2, 3), (4, 5)];
}

Result:

test.d(6): Error: cannot implicitly convert expression ([1, 3, 5]) of type
int[] to Foo[]

How/why did it reduce (.., x) to x each time?

Please read struct spec - it tells that adding a struct constructor breaks struct literals. For the question regarding why [(0, 1), (2, 3), (4, 5)] is [1,3,5] please read expression spec page about comma operator. Bugzilla is not a service for asking questions about what you do not understand - please user D.learn instead.

Then I guess put this down as just another +1 for DIP19.
