Intuitively you might expect so, but GetEventObject returns the 
'originating object' so it will be a wxWindow - or at least a 
wxEvtHandler.  wxMenuItem is a data object produced 'on demand' by 
wxMenu methods.

To do what I would guess you want without closures: (code isn't tested 
so may have typo's)

For MenuBar based menu

sub evthandler {
   my ($handler, $event) = @_;
   my $id = $event->GetId;
   my $mbar = $event->GetEventObject->GetMenuBar;
   my( $item, $menu ) = $mbar->FindItem($id);
   my $checktext = $item->GetLabel;
   ....
   ....
}


For popup, you do effectively need your popup menu 'enclosed' in scope.

my $popmenu = Wx::Menu->new(...)

...
...

sub evthandler {
   my ($handler, $event) = @_;
   my $id = $event->GetId;
   my( $item, $menu ) = $popmenu->FindItem($id);
   my $checktext = $item->GetLabel;
   ....
   ....
}
