Provide function templates for code to use instead of text areas

Computed Field allows one to write the logic in a module file instead of saving PHP directly in the database. Would you be willing to implement something like this in Views PHP? It would make the PHP in fields easier to maintain for many developer-level users (and I think most users are developers).

The idea is that I'd define a function like

function MODULENAME_views_php_field_VIEWNAME_DISPLAYNAME_FIELDNAME($view, $row);
  // Some code
}

that it will be run instead of whatever's in the text area.

_field could be replaced by _filter, _access, _cache where appropriate as well. DISPLAYNAME could be optional and take precedence over the non-DISPLAYNAME version.

Really, even a basic form of this would be awesome. Hope you like the idea.
