http://d.puremagic.com/issues/show_bug.cgi?id=2218 Summary: "builtin" typeinfos for arrays of basic types do not inherit TypeInfo_Array Product: D Version: 1.029 Platform: PC OS/Version: Linux Status: NEW Severity: trivial Priority: P2 Component: Phobos AssignedTo: bugzilla@digitalmars.com ReportedBy: tomas@famolsen.dk This is mostly just an inconsistency, but it does break some kinds of code. Namely dynamically casting for stuff like: auto ati = cast(TypeInfo_Array)typeid(int[]); assert(ati !is null); // fails Trivial to fix, just inherit from TypeInfo_Array instead of TypeInfo in the internal typeinfo directory. Probably this issue has been around forever! -- |

To get the base type of the array, call next(). -- |

That's not what I'm trying to do. I want to cast from TypeInfo to TypeInfo_Array to see if a type is an array (and then get the value type). This should be a relatively simple change and would make runtime reflection a fair bit more powerful -- not in terms of what you can do, perhaps, but certainly in terms of what information you can gather. And no, it's *not* an option to try casting to TypeInfo_Ai, then TypeInfo_Aw, then TypeInfo_Ag, ad nauseum. -- |

I didn't see that TypeInfo has next(). Still, it's extremely hacky to determine whether a type is an array by checking whether the tenth character in its classname is 'A'. -- |
