Void
Overview
A Void value represents the absense of a value. To help with type-safety, a variety of specialized operators are
available for working with Void values.
// Returns v1 if non-voidish, otherwise if `v1 == Void` returns v2
v1 ?? v2;
// Eventually the following syntax will allow optional chaining.
v3?.field();Note:
The optional chaining operator
?. has not yet been implemented or decided.
