Unfortunately, with that implementation, I need to know the
maximum size for the array. It works for that particular example,
but in the context of an XML file analysis, it's a bit awkward.

Hello,
I want to make a SAX XML parser in D that I could both use at
run-time or compile-time.
Also when I use it at compile-time, I would like to use BetterC
so I don't have to link D-runtime.
But I have some compilation problems. I use GDC (GCC 9.4.0).
