New syntax: null-aware operators

[sethladd]

Hi!

New syntax is coming in 1.12. Here's some samples:

print(exp ?? other); // prints other if exp is null

obj ??= 'hi';  // sets obj to hi if obj is null

obj?.method(); // calls method if obj is not null

The 1.12-dev SDK supports this now, if you want to try it out.

Hope that helps!
