Implement construct similar to try/catch

[perost]

I currently find myself writing code like this fairly often:

algorithm
  _ := matchcontinue()
    case ()
      equation
        // Do something which might fail.
      then
        ();
    
    else
      equation
        // Do something else.
      then
        ();
  end matchcontinue;

It would be nice to have some syntactic sugar for this kind of construct, something like:

algorithm
  try
    // Do something which might fail.
  else
    // Do something else.
  end try;

One issue with translating this into a match-statement is that you have to use equations instead of algorithms inside the try-statement though.

Does any of the developers have any feedback on the proposed try statement? The implementation issues mentioned above are not an issue since I will implement #2886 at the same time.

Fixed in r22755.
