How to use [io.stream.read]
The reference page of io.stream.read has its arguments, constraints and declaration.
Works similarly to [io.file.load] but instead of taking a source filename of some kind,
it assumes the source is an open Stream of some sort.
/*
* [.stream] here is an open stream, from for instance the HTTP
* request object, or something similar.
*/
.stream
