MergeToComprehensions

class MergeToComprehensions extends Phase

This phase merges nested nodes of types Bind, Filter, GroupBy, SortBy, Take, Drop, CollectionCast and Distinct to Comprehension nodes. Nodes can be merged if they occur in the following order:

[Source] -> Filter (where) -> GroupBy -> SortBy / (Distinct | Filter (having)) -> Take / Drop

Aliasing Binds and CollectionCasts are allowed everywhere in the chain. Any out of order operation starts a new chain with a subquery as the source.
