• After more than 30 years running websites and forums I am retiring.

    I have made many friends through the years. I will cherish my time getting to know you. I wish you all the best. This was not an easy decision to make. The cost to keep the communities running has gotten to the point where it's just too expensive. Security certificates, hosting cost, software renewals and everything else has increased threefold. While costs are up ad revenue is down. It's no longer viable to keep things running.

    All sites will be turned off on Thursday 30 November 2023. If you are interested in acquiring any of the websites I own you can Email Schwarz Network.

Any good "F# under the hood" articles/blogs?

Can anyone point me to some good blogs/articles on what exactly is happening under the hood when F# data structures are copied and updated? I think I know what's supposed to be happening but the specifics could alter how I define my records to get the behavior I want, which is for the result of a record copy-and-update to present a new structure that points to the unchanged members of the original record as well as a new allocation for each changed member, but NOT a full brand new copy of each record as they are modified.

Thanks!

Ingram
