Returning a value is already on the todo list.

You can execute the child and the parent in the same namespace by using:

Execute ({inputfile => 'foo.htm', package => __PACKAGE__, param => ['foo',
'bar']}) ;

If you want to do this you should fetch the newest CVS Version of Embperl
(or wait for 1.3b3) to avoid problems with caching, if the child page is
included in more the one parent page). Note: If you call your child page in
this way it is recompiled be every new parent page (and therefore taking up
more memory, for every page from where you call it)

If you do

Execute ({inputfile => 'foo.htm', param => \@bar}) ;

you can return a value by assingin it for example to

$param[0] in the child and then it is visible a $bar[0] in the parent.
