Hmmm, I haven't seen that much in the wild...

Ptr () corresponds to a memory location that’s pretty boring to read /

The intention in lots of APIs is quite different: A "Ptr ()" is a pointer
to some memory of unknown/externally specified format, *and* the consumer
of the API should be forced to insert explicit casts, for whatever reason.
This can be a good idea, but it can be *extremely* annoying, too, it
depends. If you don't want to force casts upon your API users, you use "Ptr
a".
