Re: getpos()

oops, 

instead of getpos() you can use line() of course:

vim9script
def g:Comment(line1: number, line2: number)
    var l1 = min([line1, line2])
    var l2 = max([line1, line2])
    append(l2, ["#endif"])
    append(l1 - 1, ["assert(0);", "#if 0"])
enddef

noremap \cm <cmd>call Comment(line('.'), line('v'))<CR><ESC>
