in thread Remove equal but different duplicates from array

Eimi Metamorphoumai,
While lc works on $_ if not specified, you can't put it in hash brackets and expect it not to be stringified (battle of DWYMisms). To make it work change it to: 
@allnames = grep(!$saw{lc()}++, @names);
# or
@allnames = grep(!$saw{lc $_}++, @names);

    Thanks everyone.

    I used:

    @allnames = grep(!$saw{lc $_}++, @names);

    Worked great!
