I see. In that case the following would be an ambiguity: ----- enum E { a, b } struct S { int x; E e; alias e this; } auto s = S(0, E.a); switch (s) // switch on 's' value or 's.e' value? { } ----- In that case I propose the subtype switch would only work if the struct has only one member which is the alias this variable: ----- struct S { E e; alias e this; } auto s = S(E.a); switch (s) // ok: equivalent to switch on 's.e' { } ----- -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
