4.9.6 Pipe links
Pipe links provide access to stdin and stdout of any program.
Pipe links are bidirectional.

The string_for system will be passed to system after conneting
the input and output to the corresponding stdout and stdin.
Example:
| link l="|: date";
open(l); l;
==> // type : pipe
==> // mode :
==> // name : date
==> // open : yes
==> // read : not ready
==> // write: ready
read(l);
