Assign (Update)

This operator is used to update node values. It can be used in either the:

plain form: =

Which will set the LHS node values equal 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, but the RHS expression is run with each LHS node as context. This is useful for updating values based on old values, e.g. increment.
