A quick thought: How hard would it be to create special notation
for accessing the ._types and ._constants objects? I was thinking
of a double underscore prefix for _types and the special "$"
character (which Mozilla JavaScript allows) for _constants:

with ( MacOS.finder() ) {

_display_dialog( "...", { with_icon : _constants.stop } );
_display_dialog( "...", { with_icon : $stop } );

_path_to( _constants.application_support, { 'from' : _constants.user_domain,
'as' : _types.alias } );
_path_to( $application_support, { 'from' : $user_domain, 'as' : __alias } );

make( _types.folder );
make( __folder );
}
