I worked out how to do it:

}
 

Or less hacky:
proc make_file_menu {app} {
     .menu.file add command -command [list $app on_quit] \
        -label Quit -underline 0 -accelerator Ctrl+Q
}
Originally you had $app inside curly braces, which prevented it from being substituted at definition time. At execution time, the app variable was out of scope.
Schelte.
