Example resultHow it works
Preserve the left-to-right method sequence and joint axis groups. Bind one sampling interval to all joint axes or bind one per axis. Distinguish area where/over selectors from climatology within/over qualifiers.
lon: maximum time: mean records the longitude maximum first, followed by the time mean. Reversing those clauses describes a different operation.
Limits
Syntax inspection only: up to 200 clauses and 32 axes each, using conservative identifier names and one unnested suffix per clause. Unknown methods are marked unsupported. Unit strings, selectors and comments remain literal; no dataset name lookup, statistics, bounds checks, UDUNITS conversion or full CF conformance verdict.
