# luan:Io.luan - `Io.stdout`: the writer that template statements and `Io.print` write to. Local cloned, so assigning it affects only this interpreter (in a web page, only this request). A page usually starts with `Io.stdout = Http.response.text_writer()`. - `writer.write(...)`: takes any number of values and writes each converted with `to_string`. Works for `Io.stdout` and response writers. - `Io.print(...)`: writes its arguments to `Io.stdout`, converted with `to_string`, separated by tabs, ending with a newline. Since it goes through `Io.stdout`, backticks capture it.
