> If you run a library in SRFI-22 mode, that should count as a program.

Generally, anything run via shebang line (#!) will be a "script" as well
as a "command" in 193's current terminology. That means the `command-*`
and `script-*` procedures return useful stuff. SRFI 22 usage should fall
under this scenario.

Are you intentionally talking about libraries (in the R7RS sense, i.e.
define-library) being run as programs with a SRFI 22 style main procedure?
