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.

New evidence in favor of a discrete form of data storage could change the way we understand the brain and the devices we build to interface with it. Mine's formatted using FAT

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.

BillWoodruff quoted: MSG Sphere will be a 360-feet-tall and 500-feet-wide concert venue
When I went o school, a sphere had to be the same height as its width. But I suppose 'The MSG Ovoid' would not sound as good as you might think it is an egg enhanced by monosodium glutamate.

My guess is that "MSG Spherical Cap" just doesn't sound as catchy.

Paleotronic was lucky enough to be given the chance to have a chat with Apple co-founder and engineer-extraordinare Steve Wozniak, who gave us a personal look into the development of the Disk II. Popping around to the shop for a thumb drive too easy?

There's no doubt that Woz is a brilliant engineer, but the interview was unreadable. Haven't the publishers of Paleotronic heard of editors? Or have English skills in America deteriorated to such a level that they can't recognize that the interview needs editing for clarity?
