Pawel Jakub Dawidek has already written a C-like language for his
Cerber project that looks like it could be used for a FreeBSD DTrace. 
It doesn't support associative arrays for stat collecting like D does,
but it's got just about everything else.  If you just wanted to track
syscalls, you could almost use Cerber as-is.
