https://issues.dlang.org/show_bug.cgi?id=20920 Steven Schveighoffer changed: What|Removed |Added CC||schvei...@yahoo.com --- Comment #1 from Steven Schveighoffer --- Typedef was meant to replace the deprecated typedef feature. If you look at D1's spec https://digitalmars.com/d/1.0/type.html, it claims that if two identical typedefs are the parameters to a binary arithmetic operator, the result should be the same type. This works today with enums as well. This should be how Typedef operates. The solution may be tricky, because one has to define opBinary for the specific type, but must forward to the base type if there is no match. --
