… comprehensions Propagates container Key and Elem size estimates through DefaultSizingStrategy, AggregateSizingStrategy, single- and two-variable comprehensions (map, filter, transformList, transformMap, transformMapEntry), cel.bind, cel.@block, and computed container indexing: - Preserves Key and Elem metadata returned on a container SizeEstimate in both DefaultSizingStrategy and AggregateSizingStrategy, and records an explicit UnknownSizeEstimate on non-empty containers whose Key or Elem size is unhinted so combining them with literal containers widens to Unknown rather than narrowing to the literal. - Evaluates comprehension LoopStep size before popping loop variables so constructed list and map accumulators (including cel.@mapInsert) carry the body's Key and Elem sizes onto the comprehension result, while clearing Key on list comprehensions. - Propagates result paths and size estimates through cel.bind before popping the bound variable and adds costBlock for cel.@block expressions.
