Proposed resolution (approved by CWG 2023-11-11):

Change in 11.1 [class.pre] paragraph 2 as follows:

The component name of the class-name is also bound in the scope of the class (template) itself; this is known as the injected-class-name. ...

Issue 2237 sought to disallow simple-template-ids as constructor names, by referring to the injected-class-name. However, 11.1 [class.pre] paragraph 2 specifies:

The class-name is also bound in the scope of the class (template) itself; this is known as the injected-class-name.

The grammar non-terminal class-name includes the option of a simple-template-id (for declaring a partial specialization).
