Why not? To me it doesn't look bad.

The compiler puts the string "XXX" into a segment (which you should
consider non-writable) and puts the address of the string into 'ptr'.

It doesn't 'declare a member of its own type' - it declares, or rather
_defines_; a _pointer_ to its own type, which is perfectly ok, since
the compiler knows a pointer's size and can reserve the appropriate
space for it.

See above.
