James, Rob, Japhy,
I am impressed, really. Thank you!
Rob, I read the perlfaq paragraph you mentioned and found that it proposes a solution
which does not make use of 'exists':
@blues = qw/azure cerulean teal turquoise lapis-lazuli/;
%is_blue = ();
for (@blues) { $is_blue{$_} = 1 }
Now, I had the idea to combine your hash slice with this solution doing:
@blues = qw/azure cerulean teal turquoise lapis-lazuli/;
@[EMAIL PROTECTED] = 1;
But since I have only a single number on the right side of the assignment function,
only one hash element gets 1. Is there a way to automatically assign "1" to all
elements with the hash slice notation (i.e. without using a loop)?
I promise to drop the subject after this question. ;)
Thanks again,
Jan
