/// @assertion The try statement supports the definition of exception handling
/// code in a structured way.
/// tryStatement:
///   try block (onPart+ finallyPart? | finallyPart)
/// ;
/// onPart:
///   catchPart block |
///   on type catchPart? block
/// ;
/// catchPart:
///   catch ‘(’ identifier (‘, ’ identifier)? ‘)’
/// ;
/// finallyPart:
///   finally block
/// ;
/// A try statement consists of a block statement, followed by at least one of:
/// 1. A set of on-catch clauses, each of which specifies (either explicitly or
///    implicitly) the type of exception object to be handled, one or two
///    exception parameters and a block statement.
/// 2. A finally clause, which consists of a block statement.
/// @description Checks that it is not a compile-time error if a catch clause
/// specifies parameters with a previously declared id.
