Nice paper. Is there a time horizon for the struct optimization mentioned in the implementation section? Is this something you're currently working on? I'm just curious.

Hi Stephan,

Thanks!

Re structs: I'd expect we'll get to it at some point in the 2.0 release cycle (of which 1.9.1 is the first part). In the meantime you can use structs to replace tuples as your active pattern return types, but you won't get the nice tuple syntax (you use properties instead, like KeyValuePair in the .NET libraries). However there is no way to replace "option" or "choice" as the partial and discrimination pattern return types.

Cheeers!

Introduction to F# Active Patterns

You may have heard of Active Patterns before – typically in conjunction with the words ‘awesome’ or ‘amazing’. Active Patterns are one of the more unique language features in F# and once you get a good feel for them one of the most powerful. This post

A question

Amar Nath Satrawala — Tue, 06 Jan 2009 18:01:50 GMT

Can somebody comment that active patterns are similar to implicit cast operators available in e.g. C#. Both need static inference. Instead of return simple objects in the case of C#, in F# records of special types are returned.

Is is a fundamental similarity here?
