You’re likely a developer and have used a code editor to debug and analyze your application failures. Few developers know or understand the “old school” way of troubleshooting to uncover additional details; enter the WinDbg debugger. "And I'm never going back to my old school"

Number one on the list of future C# features is Nullable Reference Types. But also on the table are enhancements to pattern matching, array slicing, asynchronous iterators, default interface methods, and possibly even records. Even #er?
Seems more than a bit of a repeat, but it's all in one spot, and there were a couple I don't remember seeing before.

For the first time, I think that some of these extensions are, at least as presented, getting it wrong. Semantically, many are great, but syntactically they seem to have opted for the least readable form possible...
return person switch
{
Professor p => $"Dr. {p.LastName}",
Student s => $"{s.FirstName} {s.LastName} ({s.Level})",
_ => $"{person.FirstName} {person.LastName}"
};
Seems pretty ugly. As is...
case Student ( var fn, _, "Cambell", var (_, _, ln) ) p : return $"{fn} is enrolled in {ln}’s class";
Indexing from the end of a string/array...
var lastCharacter = myString[^1];
I appreciate the features being proposed and use them in other languages, but really hope they manage to make these a bit more readable.

(disclaimer. I know near zero C#, especially at this level).
Can you ELI5 the first two examples ?
Seriously, can you ? I've got no clue what I'm supposed to look at.

Example 1:
C# 8:
return person switch
{
Professor p => $"Dr. {p.LastName}",
Student s => $"{s.FirstName} {s.LastName} ({s.Level})",
_ => $"{person.FirstName} {person.LastName}"
}; C# 7:
switch (person)
{
case Professor p:
{
return $"Dr. {p.LastName}";
}
case Student s:
{
return $"{s.FirstName} {s.LastName} ({s.Level})";
}
default:
{
return $"{person.FirstName} {person.LastName}";
}
} C# 6:
Professor p = person as Professor;
if (p != null)
{
return string.Format("Dr. {0}", p.LastName);
}
Student s = person as Student;
if (s != null)
{
return string.Format("{0} {1} ({2})", s.FirstName, s.LastName, s.Level);
}
return string.Format("{0} {1}", person.FirstName, person.LastName);
Example 2:
C# 8:
case Student ( var fn, _, "Cambell", var (_, _, ln) ) p:
{
return $"{fn} is enrolled in {ln}’s class";
} C# 7:
case Student s when s.LastName == "Cambell":
{
return $"{s.FirstName} is enrolled in {s.Professor.LastName}’s class";
} C# 6:
Student s = person as Student;
if (s != null && s.LastName = "Cambell")
{
return string.Format("{0} is enrolled in {1}’s class", s.FirstName, s.Professor.LastName);
}
Personally, I prefer the C# 7 version. But I can see the "switch expression" appealing to F# fans.

The recursive pattern (example 2) just looks horrible to me.

Oddly, I'm perfectly at home with similar features in Haskell and Rust, but somehow they just don't seem to sit well with the rest of C#'s syntax.

The problem with std::optional is that we lose information about errors. The function returns a value or something empty, so you cannot tell what went wrong. Only one is optional

That's fine - it should be used in limited circumstances where the error is obvious. For example, parsing an integer from a string will either recognise an integer or not - there really is not much more useful to say.
