There are some other differences between anonymous functions, e.g., they
don't honor PRINT_EXIT_VALUE:

    % setopt printexitvalue
    % () false


    % setopt printexitvalue
    % f() false
    % f                                                            
    zsh: exit 1

Engineering-wise, the ideal solution would be for anonymous and named
functions to share code... though I realize that may be a somewhat
invasive code change.
