Talk:Top type

Merge
Someone added a merge tag, but did not actually start a discussion. So here it is. I think that the "right thing to do" would be keep two articles, to move the section on "programming language support" in this article to singly rooted hierarchy, while leaving the rest of this article as a more theoretical discussion of the role of a top type in theoretical type theory. 99.153.64.179 (talk) 19:30, 26 June 2013 (UTC)

C++ std::any is not an universal base class
As std::any can store only copy constructible types and there are types that can't be stored in it (for example std::unique_ptr), std::any is not universal enough. DkD2000 (talk) 17:22, 6 May 2022 (UTC)
