literal top-level constant
Used to annotate a const constructor
c. Indicates that any invocation of
the constructor must use the keyword
const unless one or more of the
arguments to the constructor is not a compile-time constant.
Tools, such as the analyzer, can provide feedback if
- the annotation is associated with anything other than a const constructor, or
- an invocation of a constructor that has this annotation is not invoked
constkeyword unless one or more of the arguments to the constructor is not a compile-time constant.
