>+        From https://tc39.github.io/ecma262/#sec-block-static-semantics-early-errors:
>+        It is a Syntax Error if any element of the LexicallyDeclaredNames of StatementList also occurs in the
>+        VarDeclaredNames of StatementList.
>+        
>+        This patch handles the { let x; { var x; } } scenario; a patch to handle { { var x; } let x; } will follow.
>+
>+        When checking for existing lexically declared names, we can't simply check the current var scope;
>+        we need to check *all* enclosing scopes up to (and including) the current var scope. In so doing,
>+        we must also avoid violating the Annex B.3.5 condition that permits `try {} catch (e) { var e; }`.
