Thank you for your response.

Can you elaborate on 'write struct...'? Is that special syntax? I 
assumed so, but dmd doesn't like it. I also checked to see if you 
meant "(manually re-write it as...)", but updating the struct 
definition in the generated .d header with field values doesn't 
seem to solve the __initZ issue, either. And redefining it in the 
client .d module just shadows the header definition, so ...
