Thanks! No, I didn't have any real problems at that time. I used 
very few packages outside the standard library, and the ones I 
used weren't outdated yet. However now, a few years later, it 
might be hard to build that code and make it work.

The biggest killer feature here is D's static introspection. It 
allows easily calling to native code libraries from your 
interpreter without a complicated FFI layer. You take an existing 
D struct, class or just function, mention it to the interpreter 
("register" it), and all its necessary members become 
automatically accessible from your language, with all the 
conversions from interpreter's data types to native data types 
happening automatically, all the access & conversion code is 
autogenerated using D metaprogramming and static introspection.
Also, having a GC in D means we don't have to make our own GC for 
the interpreted language. On the other hand, when we want to 
control the low level bits of memory layout etc. we can still do 
it.
