What language does the undocumented option (assuming

generates a completely different and as far as I know undocumented
language, which is handled by the execute function (in execute.c) but as
far as I know there is no way to make it accept it on standard input.
Standard bc:
$ echo '2+2' | bc -c
2 2+ps.

GNU bc:
