When calling my script with:
    dummy.scm "temp/input" "dummy.log" "^ +" "1234567890"
it is just executed.

When starting Guile, I give:
    (load "bin/dummy.scm")
and then:
    (main "temp/input" "dummy.log" "^ +" "1234567890")
and I get:
    Backtrace:
    In standard input:
      10: 0* [main "temp/input" "dummy.log" "^ +" "1234567890"]

    standard input:10:1: In procedure main in expression (main "temp/input" "dummy.log" ...):
    standard input:10:1: Wrong number of arguments to #<procedure main (args)>
    ABORT: (wrong-number-of-args)

when I use:
    (main ("temp/input" "dummy.log" "^ +" "1234567890"))
I get:
    Backtrace:
    In standard input:
      11: 0* [main ...
      11: 1*  ["temp/input" "dummy.log" "^ +" "1234567890"]

    standard input:11:7: In expression ("temp/input" "dummy.log" "^ +" ...):
    standard input:11:7: Wrong type to apply: "temp/input"
    ABORT: (misc-error)

So how should I call it from the REPL?
