 Note: if the parser was in error-recovery mode, some AST nodes may have
 null children that are expected to be non-null
 when no errors are present.  In this situation, the behavior of the
 toSource method is undefined: toSource
 implementations may assume that the AST node is error-free, since it is
 intended to be invoked only at runtime after a successful parse.
