Source code. Test it running 'dub'.

I get a strange error with dmd 2.069 b1.
I can't understand what happen exactly but apparently traits allMember return
an unrelated symbol.

I reduced code using dustmite and manually. 

Attached code compile for me using dmd 2.068 on linux x64. 

Using dmd 2.069 b1 it fails:
source/tests/utils.d-mixin-13(13): Error: undefined identifier
'_D32TypeInfo_S7asserts12AssertResult6__initZ'
