[Pdx-pm] I think that I'm trying to make things too hard.

	While this works, I tend to use {}s around variable names
to disambiguate them inside double quotes:

$data->{body} = &{"local::${action}::generate_page_data"};


$data->{body} = &{ 'local::' . $action . '::generate_page_data' };

that way you don't have to remember the precedence rules when/if
$action::generate_page_data is defined. But, ah, you're right about it
being something to generally avoid in the first place.
