C++ provides many features that have unspecified implementations -- a
mark of a high-level language. It is challenging to implement some Perl
features, like dynamic module loading, and still be able to use some
features of C++, such as static object initializers. Also, binary
compatibility between releases becomes much harder because vtbl layouts
and inlines have to be watched just as much as struct alignments.

If we constrain ourselves to using C++ as a "better C", then the problems
go away. I proposed such an implementation way back when Topaz was first
starting, but Chip decided to go with an implementation more true to C++.
Either way brings benefits and challenges and there's no clear superior
solution -- community by-in IMHO is the most important architectural
feature there is.
