Description
The warning text in the doc says:
'Warning: For trait objects, if there is an inherent method of the same name as a trait method, it will give a compiler error when trying to call the method in a method call expression.'
https://doc.rust-lang.org/reference/expressions/method-call-expr.html
However, the following Playground code compiles and calls the trait object method: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=ee3edd82619f479bdc9980c03b2f201f
This suggests that the warning is incorrect, and should be deleted.
