Hi @Troyblants!
Thank you for the PR!

I like the genereral "core" direction you are going here, (adding a third argument with context and variables to the mutation's update method), but I have to be honest: these TypeScript changes are a bit too much.

Generally, we probably need to move away from generic declarations like this, as they are more akin to an any-cast than actually providing any type safety (you could call mutate 20 times with completely different contexts, and the Link chain would not know to make anything of at least 19 of them).

I know, a lot of work has gone into adding those generics everywhere (and I'm really sorry to ask this of you 😞), but could you please do the PR without them?
