Re^2: desire hard ref alternative

Even without reading the code, you can prepend use strict; and run it; and Perl will tell you:

Can't use string ("") as a HASH ref while "strict refs" in use at ./3o
+.pl line 25.

So, here:

                next if(exists $$href{$word}{written});

ok, so $$href{$word} is not a hashref , its a string... so it can't have an written key :)	[reply]
