Hoist

[benmccann]

Describe the problem

We should be able to use unchanged primitives directly in template values. This would shrink the size of the compiled output

Describe the proposed solution

I implemented it in #10015. However, Rich wanted to take a more holistic approach to hoisting. I'm not nearly experienced enough to do that or even understand what it would mean, so hopefully someone a bit more expert can take a run at it

Importance

nice to have
