2 flaws I've found so far:

you can't name data, such as:
hello db "Hello, world!$"

and, do register names really HAVE to be upper-case? Why can't they be lower
case, too?

 2 flaws I've found so far:

Add a : after the label:

    hello: db "dddd";

 and, do register names really HAVE to be upper-case? Why can't they be

lower
 case, too?

Because it has to tokenize like the rest of the D language, and keywords are
case sensitive. It makes it a lot simpler.

any suggestions?

mov DX, offset hello;

error: bad type/size of operands 'mov'

too big of a memory address?
