Talk:Extension by definitions

I challenge low-priority

I consider it wrong to give long priority to this article, because extension by definition is used in _every_ math book (except of ones based on lambda-calculus). So widely used concept should not be considered low priority! VictorPorton (talk) 03:07, 7 August 2022 (UTC)[reply]
