There's also the cut operator which I didn't see mentioned in the RFC.
It blocks backtracking so that something like this:

They behave similarly like , ||, and, or operator with one main
distinction they "backtrack" for example:
{ block1 } Bandthen { block2 };
This would be a good use of the to-be-liberated = operator:
{ block1 } = { block2 };
In any case, "andthen" doesn't seem like a good choice.
