[New-bugs-announce] [issue36524] identity operator

[Rocco Santoro]

New submission from Rocco Santoro <rojorougered at hotmail.com>:

Hi all

Why the identity operator and '=='  are both applied to the type (see above)? Is it not convenient to distinguish them? I mean the identity operator  applied to the type and '==' applied to the outcome.
Thanks for the attention
Best regards
Rocco Santoro
