digitalmars.D.bugs - [Issue 15554] New: typedef standard type can't be used with to!


          Issue ID: 15554
           Summary: typedef standard type can't be used with to! properly
           Product: D
           Version: D2
          Hardware: All
                OS: All

Casting from a string to a custom Typedef type is more complicated than it
should be. To should actually care about the underlying typedef-type, and
recognize that it has to parse a string to a long value:

alias QuestionId = Typedef!(long, long.init, "QuestionId");

QuestionId q = to!(TypedefType!QuestionId)("43"); // Compiles
QuestionId q2 = to!QuestionId("43");              // Error..
