Reading `process.stdout.write` as a value, `write.bind(stream)`, and
`process.stdout.write = fn` now reach the runtime stream object's write
slot in TypeScript, and a program that replaces an output write method
calls its typed writes through that slot (SC8020 refuses the combination
with Node islands until H2 shares the stream object with them).
