           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!

You shouldn't need to ever cast to TypeInfo_Array. To get the base type of the
array, call next().

What is the point of TypeInfo_Array then?

I understand that I should never have to cast from TypeInfo_Ai to TypeInfo_Array. 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.

HAHAHA DISREGARD THAT.

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'.
