Hi,
1) I program in C# and I'm wondering if there is something
like ?? (Null-Coalescing Operator) in D? (I remember some
proposals in the past).
Not in the language but it can be implemented as a library
function by overloading "opDispatch". See [1] for an example.

In the same vain there's "safeAccess" in my user library, see
https://github.com/BBasile/iz/blob/master/import/iz/sugar.d#L1658. It's more or less the same specific D pattern (opDispatch), although the OP asked for "??" and not for "?.", which is strange. I find that the later misses more as a builtin operator.
