   = (lambda (m) (void))
Creates a new menu with the given label.

If label contains a &, it is handled specially; on Windows, the character following a & is underlined in the displayed menu title to indicate a keyboard mnemonic. Pressing and releasing the Alt key switches to menu-selection mode in the menu bar where mnemonic characters are used for navigation. An Alt combination might select a specific menu via on-menu-char. A && in label is replaced by a literal (non-navigation) &ampersand. On Unix and Mac OS X, &s in the label are parsed in the same way as for Windows, but no mnemonic underline is displayed.

If help-string is not #f, the menu has a help string. See get-help-string for more information.

The demand-callback procedure is called by the default on-demand method with the object itself.
