   my @numbers = (4,7,11,14);

print join ' ', map { 0, $_ } @numbers;

The code above gives this:

Not enough arguments for map at 910662.pl line 9, near "} @numbers"
syntax error at 910662.pl line 9, near "} @numbers"
Execution of 910662.pl aborted due to compilation errors.

I tried this:

print join ' ', map { ' 0 ' . $_ } @numbers;

And get this:

 0 4  0 7  0 11  0 14

Not sure where the extra spaces after 4,7 and 11 come from.

Update: duh, the join has a space.
