Excellent tool - I'll use it more. I'm using a version of the 
trunk from not long ago and the dmd version output from "dmd -v" 
is 2.061. dpaste does not provide 2.061 as an option. The 
difference in error messages is between 2.060 and 2.061 (i.e. if 
I use my 2.060 I see same message as you - more detailed==better).

Not to me. Sorry if I'm missing something, but a solution would 
be that it not only compile, but it invoke my this(const this) 
postblit, which unless I'm missing something it does not.

Look at this: http://dpaste.dzfl.pl/95d40612
I commented out this(this) and dmd is happy, but I am not because 
nothing is printed. This is quite bad because I think I'll be 
duping all my members but it won't get called and sharing will 
ensue. What am I missing?

Thanks,
