Perl6's use of sigils seems excessive to me but I do like sigils for variables. It acts like a namespace between similarly named constructs. I know for instance WebClient is a class and $WebClient contains an instance of it. I also like how it makes it easy for syntax highlighters to identify variables from classes and keywords.
