Belay that, the behavior is as designed, I think the issue is the 
documentation.

If arraySep is "", then it's not "separation by whitespace", but rather 
you must repeat the parameter and each one is appended to the array:

dmd -run sample.d --modelicalibs a --modelicalibs b

If you want to specify all the parameters in one, you have to provide an 
arraySep.

The documentation needs updating, it should say "parameters are added 
sequentially" or something like that, instead of "separation by whitespace".
