That should read
"the one defined in the LATER file wins"

Blah blah blah, write a pragma, blah blah blah.
I tend to agree on generic -> specific, but if it is to be read like
given/when in a way, which arguably it is behind the scenes, then
maybe we should make given { } take the statements in a block and
execute them from last to first?

It isn't a tree... see below

This is pretty match the same as what I proposed...
The sub points are usually clarifications, not a tree.... Did you
actually read it?
It discusses types, roles, inheritence, and so forth, as well as
measuring the "specifity" of junctions of values and types. It's
long because it goes into detail.

I agree with simplicity.
Please read the sequence i proposed - it's trying to define with
great detail the simplest rules I can think of.

That's why under the fourth steps I detailed that MI confusions are
a fatal error, possibly at compile time.
