Happy it helps! Spent a night figuring this out ... simple once you see it all together :-)

comment How to implement FittedModel like objects
Okay, in the end @LeonidShifrin was right ... I do really want to understand how to use DownValues/SubValues to actually implement the type of behavior something like FittedModel has. Now I am going to try and do this on my own for a bit, but when I want to ask it ... is there a way to make it clear that this is not covered by the linked to question (which just deals with the Format/Boxes issue)?

@LeonidShifrin thanks ... I was doing it on a variable that contained a FittedModel not on FittedModel itself. Confusion is slowly clearing. Thanks!

@LeonidShifrin a FittedModel doesn't seem to have SubValues either ...

nah the close is fine. I tried searching as I had vague memories of this issue. The SubValues solves the issue well enough for me. Thanks

Have you kept up with this project at all? I would be interested in seeing the github if it exists.

@Szabolcs can you give your other example as an answer with the Boo example. This seems like the smoking gun for me that it is a bug and not a safety net. I can accept that and issue the bug report.

comment NDSolve and {C, K, Slot} and other built-ins as a variable name
@Szabolcs yes thanks I like these points. More what I am trying to get at. You are saying that it is a specific test that Mathematica is doing to try and stop the user from getting errors. It is not something that I will be able to ever trigger with my own definitions that get shadowed since must be somehow tested for by NDSolve itself (and if so it should do the same in DSolve, 1D cases etc) and I should file a bug report.

comment NDSolve and {C, K, Slot} and other built-ins as a variable name
I like this answer the most so far, as I find the idea intriguing that it is some kind of symbolic preprocessing that is causing the error. I wish I could think of a way to test this with a built in symbol that would never arise in such a context as C K and Slot all might be candidates for this
