The attribute-token nodiscard may be applied to a function or a lambda call operator or to the declaration of a class or enumeration. An attribute-argument-clause may be present and, if present, shall have the form: ( unevaluated-string ) 2 # A name or entity declared without the nodi...
The intent is to avoid lambda-expressions appearing in the signature of a function template with external linkage.— end note] For determining whether two dependent names ([temp.dep]) are equivalent, only the name itself is considered, not the result of name lookup. [Note 5: If such a...
I will cover a practical technique to implement "lambda-like" HTTP services behind RPC-as-message-passing gateways withZIOandTapirlibraries. The advantage of such an approach is that you can keep the business logic and interfaces of the service(s) separate from the transport layer; and since t...

(1.5) An rvalue is a prvalue or an xvalue. 2 # Every expression belongs to exactly one of the fundamental categories in this taxonomy: lvalue, xvalue, or prvalue. This property of an expression is called its value category. [Note 1: The discussion of each built-in operator in [...

Change: Decrement operator is not allowed with bool operand. Rationale: Feature with surprising semantics. Effect on original feature: A valid C expression utilizing the decrement operator on a bool lvalue (for instance, via the C typedef in <stdbool.h>) is ill-formed in C++. 4 # Affected ...
