But grepping on  $_ filters out the string  '0' or a numeric value of 0. 

>perl -wMstrict -le
"my @Array = ('A', undef, 'B', '0', 'C', 0);
 print join ' ', map {qq(\"$_\")} grep { $_ } @Array;
"
"A" "B" "C"

Grepping on length will allow handling of  '0' or 0, but is unhappy with an undefined value (if this should be an issue). 

>perl -wMstrict -le
"my @Array = ('A', undef, 'B', '0', 'C', 0);
 print join ' ', map {qq(\"$_\")} grep { length } @Array;
"
Use of uninitialized value in length at -e line 1.
"A" "B" "0" "C" "0"

Grepping on both defined and length handles a broad range of variations. 
>perl -wMstrict -le
"my @Array = ('A', undef, 'B', '0', 'C', 0);
 print join ' ', map {qq(\"$_\")} grep {defined and length} @Array;
"
"A" "B" "0" "C" "0"
