Array to hash

| Perl | 2 Comments

Ever wondered how to quickly convert an array to a hash on the fly? Well here's one way to do it:

my %h = map { $_ => 1 } qw/one two three four/;

Feel free to come up with other perhaps more efficient and/or elegant and/or cryptic ways of doing this.

my %h; @h{qw/one two three four/} = undef;
