Thanks! The complete text is:

"According to Walter in the January 2023 Quartely Meeting, sum 
types won't be the focus in D anytime soon, in favor of 
robustness. That's 100 % reasonable. But if sum types appear, 
non-nullable class references can go hand-in-hand with them: The 
nullable reference ("X" in D2, in other languages "X?") is really 
a sum type of the non-nullable reference ("X") and typeof(null). 
And "?" can become universal shorthand for "sum type with 
typeof(null)" not only for non-nullable class references, but for 
any type."
