Feature request catch expression in future .Net release

[yaddly]

The .Net framework introduced a switch expression to replace the switch structure:

string result = domain switch
{
    "us" => "United States",
    "de" => "Germany",
    "sk" => "Slovakia",
    "hu" => "Hungary",

    _ => "Unknown"
};

This new expression got me thinking if it would not be ideal to have a catch expression as well.

try
{}
catch (error) => {
  error is FormatException => {},
  error is ArgumentNullException => {},
  error is IndexOutOfRangeException => {},
  _ => {}
}

The above feature request is more elegant than the conventional use of multiple catch statements.

Similar to (but quite the same) as #989.
