Re: Sigils in Classes after initial "has"

If you declare a private attribute

has @!items

then all your references to that attribute have to include that sigil.

If you declare it with the dot sigil:

has @.items

then it creates an accessor, so that self.items or @.items work for
accessing, as well as @!items.

You can also declare

has @items;

in which case a private attribute @!items is declared, with a lexical
alias @items (without any twigil).

This could become a FAQ entry...
