Data Point: Power Query's "M Language"

[DavidPratten]

Hi,

Random observation. Not sure if it is interesting or not.

Power Query's "M Language" shares some heritage and goals with Morel.

On the technical side, in a nutshell, M is a functional language, sharing similarities with languages like F# and Haskell. Specifically, it’s mostly pure, higher-order and partially lazy. ... Primer

The language is built on top of a query optimiser that re-orders and transforms queries and can pass them to a database for execution. Query Folding.

Curiously, despite its "Swiss-Army Knife", and "all batteries included" approach, M Language lacks support for recursive, fix point queries and is unable to handle trees and graphs.

Thought this was an interesting data point.
