A member function can be declared (but not defined) using a typedef for
|
| 70 |
a function type. The resulting member function has exactly the same type
|
| 71 |
as it would have if the function declarator were provided explicitly,
|
| 72 |
see [[dcl.fct]]. For example,

definition, the parameter type `T` refers to the typedef member `T`

static data member `count` declared in class `X`.
