RFE: feedback loops
 

A relatively easy implementation would be to fiddle shell commands:

if (LASTCHAR(p) == '|')
error(FATAL_RESTART, "pipe to nowhere?
");

to interpret pipes to nowhere to, instead, be redirecting to a mkstemp file
that gets read back in via an internal:
sprintf(pc->command_line, "< %s", tmp_file);
after the command completes, and
unlink(tmp_file);
after *those* commands complete.

What you already have works. It's that this would be slick :).
It would make shell scripting into a crash extension language.

Submit a patch and we'll take a look...
