I'm not sure what this is, it might be from my code but it 
doesn't list the file

It would be nice to

1. Disable any mixin outputs to the mixin file(unless they are 
required by D, but I think they are not?) from phobos(maybe make 
it optional)

2. Alow one to disable the output to the mixin in a single file(a 
pragma such as pragma(mixin, off);pragma(mixin, on);). This might 
require something on D itself.


and one has zillions of

It's a compiler generated mixin for hash calculation. I agree, should be
omitted.

 
 It would be nice to
 
 1. Disable any mixin outputs to the mixin file(unless they are required
 by D, but I think they are not?) from phobos(maybe make it optional
 
 2. Alow one to disable the output to the mixin in a single file(a pragma
 such as pragma(mixin, off);pragma(mixin, on);). This might require
 something on D itself.
