This operator is used to update node values. It can be used in either the:
### plain form: `=`
Which will assign the LHS node values to the RHS node values. The RHS expression is run against the matching nodes in the pipeline.
### relative form: `|=`
This will do a similar thing to the plain form, however, the RHS expression is run against _the LHS nodes_. This is useful for updating values based on old values, e.g. increment.

Updates the LHS using the expression on the RHS. Note that the RHS runs against the _original_ LHS value, so that you can evaluate a new value based on the old (e.g. increment).
