Re^2: undefined elements in array
in thread undefined elements in array
I think you meant grep, not map:
0:14 >perl -wE "@a = (1,2,3,undef,5); say scalar @a; @b = map(defined
+, @a); print join(',', @b);"
0:14 >perl -wE "@a = (1,2,3,undef,5); say scalar @a; @b = grep(define
+d, @a); print join(',', @b);"
