No, I'm sorry.  I'm still collecting information and exploring 
ideas to build my case.  You mentioned in on one of the recent 
PRs that you believe something like `opImplicitCast` could be 
implemented without some of the drawbacks present in C++'s 
implementation.  I'm interested in your ideas.

I need to make a strong case, so I'm exploring how to motivate my 
idea and I'm trying to discover any holes in it.  There's also a 
DMD bug I'd like to resolve before submitting a DIP.

In general, my idea is to create a more limited `alias this`-like 
feature that will eliminate some of the "weird sh**" that comes 
with `alias this` and only keep the good stuff.  Whatever's left 
can be implemented with D's existing metaprogramming facilities.

I believe it could be approved because it will significantly 
reduce the compiler's implementation and avoid a lot of bad 
interactions.  I think that would be appealing to Walter and 
others.

If you want to discuss it you're welcome to contact me on Slack, 
Discord, or IRC under the handle JinShil and I'll give you all 
the details of what I have in mind.
