The cause: if run interactively guiles default module is 'guile-user', if
run from a script it is 'guile' (humpf!). Try the following:
| bash-2.05$ guile
| guile> match:string
| #<procedure match:string (match)>
| guile> (define-module (guile)) ; what is active when run as a script
| #<module (guile) 8081620>
| guile> match:string
| ERROR: Unbound variable: match:string
| ABORT: (unbound-variable)
| guile> (define-module (guile-user)) ; back to interactive guile-user
| #<directory (guile-user) 80835c0>
| guile> match:string
| #<procedure match:string (match)>
| guile>
|
You need to import match:string from (ice-9 regex) if you want to use it from
within a script.
Hmm, thinking of it -- why is (ice-9 regex) loaded in (guile-user) ?
