Note: the standard doesn't define a named requirement with this name. This is a type category defined by the core language. It is included here as a named requirement only for consistency.
Requirements
The following types are collectively called implicit-lifetime types:
array types
cv-qualified versions of these types
Notes
Certain operations may
and start the
of objects of implicit-lifetime types, if doing so would prevent
. However, such operations do not start the lifetimes of subobjects of such objects that are not themselves of implicit-lifetime types.
Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
