Ah yes :) that's very true !  scalar @array is, of course, much better !

( i did meant the undef value, btw, and not the string 'undef' but it's true that my use of single quotes was indeed a bad idea !! )

I'll add something : suppose the OP wanted to undef arrays in a sub . I think I would pass the array as a reference, undef it in the sub and return the reference .
