I suspect that the traditional implementation stems from the lack of
redirection on built-ins in the orginal shell, but I could be wrong.
Binding would matter the implementation of a pipeline avoided
unnecessary forks (my order of binding would mean that the read rather
than the echo was run in the current shell).
