So are you saying that "a??.b.c" is NOT equivalent to "a?.b?.c"? With
this implementation of "??", a NPE is thrown if a is not null but a.b
is...
with this implementation we talk about my example here. That is not what
is implemented right now. May pint is that in my version the null check
stops the evaluation of the remaining expression, while the current ??.
does it for each part.
