`EXP52-CPP`: Exclude uses of operators with unevaluated operands in already unevaluated contexts

[lcartey]

Affected rules

• EXP52-CPP

Description

Exclude uses of operators with unevaluated operands where they are already in unevaluated contexts, as the scope for confusion is less.

Example

template<typename T>
void foo(T t) noexcept(noexcept(some_function(t))) {
  some_function(t);
}
