Detailed Description

Concept for inspection functions that observe but don't modify values.

The function must be invocable with the value type and return void. Supports both direct invocation and std::apply for tuple unpacking. Allows const ref consumption even if the original type is just ref or value.

Template Parameters

Func	Function type
ValueType	Type of values to inspect
