that behavior does not generate an error; and it was mentioned all the
other `_ptr` types (unique_ptr) being part of that.
My primary use case is back-porting changes to code that was ported from C
to JS. And C that compiled as C++, and taking those changes and back
porting to the original C...
In this case '.' generates a compilation error, and there is no alternative
meaning to '.' currently that would apply.
