Erlang has had a construction like this for some years now.

try Expr of
  Pat1 -> Clause1;
  Par2 -> Clause2;
  ...
catch
  Class:Error ->
    ...
end

Of notable semantics, the exception only reaches over the scope of Expr and
not over ClauseN. In practice, I have used it quite often in Erlang-code.
