No time to dig deeper but this is because the two ranges that

This is related to TypeInfo.init, which unfortunately is *not*
the .init property in this case. :( Luckily, it will be fixed
in 2.075. This is what object.d has:

So, unfortunately, most Phobos range functions cannot be used
with TypeInfo as they would invariably touch ElementType. Here
is a halfway workaround that uses each() instead of map(): :/
Aaah, so I was not doing anything wrong ;-)
I was trying to factor this code:
foreach (i; k.interfaces) {
if (i.classinfo in classMap) {
v.bases ~= classMap[i.classinfo];
}
}
if (k.base in classMap) {
v.bases ~= classMap[k.base];
}
i.e. process the class base along with the interfaces in the same
loop. I dwelled on it because my goal with this project is to
learn (and evaluate) D.
Anyway, I am building my own graph of enriched ClassInfo objects;
once that is done, I won't be impacted with the bug anymore.
Thanks for the diagnostic...
