So that you know, the state of play is:
* wip/spj-wildcard-refactor is fully up to speed with HEAD
* It validates except for perf/compiler/T3064 (8% loss)
* It does need a decent commit message
I'd really like this in 8.0:
- It's a big patch, so not having it will lead to lots of
tiresome cross-branch porting
- It does fix things in the wildcard story
Of these the former is the more important.
The only think holding me up is that I really don't understand the perf regression. It seems to be in the simplifier, which I have not touched! Working on it. But in the worst case I can commit and open a ticket for the perf regression
