[ENHANCEMENT]: filter support values on both sides of compare functions #8636
Description
Use case and current behavior
It is useful to compare variables computed on selected nodes.
For example :
Type A as relationships to B and C. Find the node A which have the same number of relationships to B and to C.
Enhancement
@filter(eq(val(firstCount), val(secondCount))) should be supported.
