I have a perl script like this:

$ cat foo.pl
... snip ...
# these functions are exposed to users
sub func1 { 
  say "func1 arg: " . $_;
  ...
}

sub func2 {
  say "func2 arg: " . $_;
  ...
}

sub func3 {
  say "func3 arg: " . $_;
  ...
}

...

This is a script users will invoke, simply by doing something

$ ./foo.pl


in the current working directory, the user will have a file like this, which is also a perl script, but looks a bit more like a domain specific language. it uses functions from foo.pl:

$ cat userscript.pl
func1 'test1';
func2 'test2';
func3 'test3';
$ 

So if you were to execute my script, with userscript.pl in the current directory, you may see something like this:

$ ./foo.pl
Loading userscript.pl...
func1 arg: test1
func2 arg: test2
func3 arg: test3
$
