Hello. I have an array of characters that I would like to be able to pattern match against. I've written the following code: 
@a = ( 'a', 'x', 'z' ); # simplified array
while(<>)
{
   print if(/^[@a]{3}$/);
}

This works well, except that it also accepts space(' ') as a valid character. I've also tried to use join ('', @a) but it gives the same results. Can anyone explain to me why this happens? Thanks.
