I'm surely overlooking something simple here, but what's the syntax for turning an array into a hash. I'm trying to eliminate the superfluous %words in the code below... 
#reduces a file to a sorted list of unique words

my %words=map {$_,1} grep /^[a-z]+$/, (split /\s/, join(" ",<>));

print "$_\n" for sort keys %words;
