Summary:                    String concatination
Description: 
Code:

module Test
{
  Main () : void
  {
    _ = "" + match (1) { | 1 => "" | _ => "" } + ""
  }
}

Error: cannot find the operator `op_UnaryPlus' on string

The following works fine:

module Test
{
  Main () : void
  {
    _ = "" + (match (1) { | 1 => "" | _ => "" }) + ""
  }
}

This is a parsing problem. The code above is parsed as:

_ = "" + match (1) { | 1 => "" | _ => "" };
+ ""

I'm not quite sure this can be easily changed. As of now the parser always
thinks there is a ';' after '}'

Yeah, so I guess we sould close it as "by design" - this feature was done
to make following code patten possible:

def f() {
  while (x) {
    ...
  }
  -count;
}

This is ugly, but by design
