public class TrySymbol
extends ControlSymbol

EK9 try statement - this can effectively return a value if it is configured with returning part. When generating out put we need this to create its own block so variables inside are hidden from later scopes. So as we have a returning part (optional) we need a scope to put it in (i.e. this scope) this then means that when we use the catch and finally parts of the try we can find that returning variable.
