Code: enum Pieces : ubyte { Empty, Pawn, Rook, Knight, Bishop, Queen, King } int color = 0b10000000; ... byte[64] pieces; ... pieces[i] = color ^ Pieces.Rook; Explanation: The compiler marked the error as occurring in the enum saying that 129 was too large to store in a byte when the error should have occurred in the last line where 129 was actually being assigned to a byte value.
Thanks for reporting. You reduced/edited the code a bit too much. It doesn't actually show the problem anymore. But don't worry, I got you. Here's reduced code that still shows the wrong error message: ---- enum Pieces {Rook} /* line 1 */ immutable int color = 0b10000000; byte piece = Pieces.Rook ^ color; ---- test.d(1): Error: cannot implicitly convert expression (128) of type int to byte ---- For reference, this originated at Stack Overflow: http://stackoverflow.com/questions/32681660/compiler-thinks-enum-values-are-starting-at-129
