The TypeSwitchGuard may include a
<a href="#Short_variable_declarations">short variable declaration</a>.
When that form is used, the variable is declared at the beginning of
the <a href="#Blocks">implicit block</a> in each clause.
When that form is used, the variable is declared at the end of the
TypeSwitchCase in the <a href="#Blocks">implicit block</a> of each clause.
In clauses with a case listing exactly one type, the variable
has that type; otherwise, the variable has the type of the expression
in the TypeSwitchGuard.
