Trying to play with introspection.
trying o, for a given object, to check its property by name.
Experimenting with the function below.
1. it doesn't compile! mi.name() seems to be a problem?
2. match is always null! even though I pass the name of an existing property
and / or field!
trying to learn introspection, I have this simple test method:
===
static void dumpelement(Object o)
{
if (!o)
return;
auto ci = o.classinfo;
foreach(mi ; ci.getMembers(null))
{
writefln(%s . %s, ci.name, mi.name());
}
}
==
However

Interesting... I think I understand...
Thanks! :)
However an other problem arise with getMembers() it always returns null!
Looking at the code it seems (from my beginner's perspective) that
getMembers() rely on the member field (function) xgetMembers which is always
null, as far as I can tell

Thanks Robert!
Mm.. can you (per chance!) share some code?
I'm a newbie and compile time reflection is something which eludes me (so
far...)!

Anyway of ... making the runtime update xgetMembers?
My understanding

Works a treat!
Thanks for your detailed sample! :)
