[description]
[para]
The [package tcl::chan::std] package provides a command creating
a standard channel which unifies stdin and stdout into a single
read- and writable channel. The result is not seek-able, like
the original standard channels.
[para] The internal [package TclOO] class implementing the channel
handler is a sub-class of the [package tcl::chan::core] framework.
[section API]
[list_begin definitions]
[call [cmd ::tcl::chan::std]]
This command creates the std channel and returns its handle.
[para] The channel is created only once, on the first call, and all
future calls simply return this handle.
