This is just about 1/100th of what is output for a near empty project:

It makes it hard to find one's own mixins in the output.

2 suggestions:

1. consolidate outputs, this should reduce the file size by over 50%!!!
2. Ignore phobos mixins(rarely will one need to see the output of phobos mixins as they are generally going to be valid)

Of course, these could be optional.

Also, one gets a lot like


// expansion at
size_t h = 0;foreach (i, T; typeof(p.tupleof))    static if(is(T* : const(.object.Object)*))         h = h * 33 + typeid(const(.object.Object)).getHash(cast(const void*)&p.tupleof[i]);    else         h = h * 33 + typeid(T).getHash(cast(const void*)&p.tupleof[i]);return h;

// expansion at
size_t h = 0;foreach (i, T; typeof(p.tupleof))    static if(is(T* : const(.object.Object)*))         h = h * 33 + typeid(const(.object.Object)).getHash(cast(const void*)&p.tupleof[i]);    else         h = h * 33 + typeid(T).getHash(cast(const void*)&p.tupleof[i]);return h;

"expansion at"??????? Where is it?
