Hi, if you're just looking for other ideas, you might want to
look at adding capabilities like in the java hamcrest matchers.
You might also want to support regular expression matches

Take a look at FileDescriptor[1]. It is a class I've added to
support read/write using File from std.stdio. You can create a
similar streamer using std.mmfile. I believe that this would be
enough for memory mapped reading.

I did test with the libc strlen, although the D libraries did not

oops. I see ... need to test for empty string.

I'd say use this one instead, to avoid negative size_t. It is
also a little faster for the same measurement.
nothrow pure size_t

After watching Andre's sentinel thing, I'm playing with strlen on

Seems to work and is 4x faster compared to the runtime version.

Very nice.
I wonder about representation of references, and perhaps
replication, inheritance. Does SDL just punt on those?
