Instance Method Details

#bytecode(g) ⇒ Object

When a script includes __END__, Ruby makes the data after it available as an IO instance via the DATA constant. Since code in the toplevel can access this constant, we have to set it up before any other code runs. This AST node wraps the top node returned by the file parser.
