You are right. What I should have said is: "the lack of sigils to indicate type of a variable". In perl this noise is everywhere, while in Ruby its is a lot less common.
Specially if you use accessor methods. In ruby, unlike smalltalk, this instance variable sigils are pretty much impossible to get rid off. This is because in Smalltalk local variables have to be declared, and if you don't, the Language will try to use the instance variables. In Ruby it would default to being a local variable, if already assigned, or invoking a method with no arguments.

Ruby even uses some predefined globals (eg $_) that are pretty much straight out of Perl.

They exist, and while I'm a fan of $: over $LOAD_PATH I don't think I've even seen $_ used in the wild.

I don't really have the perspective to comment on how common they are, but they do exist. Ruby is full of little things like this, which one of the things I simultaneously love and hate about Ruby
Okay, I don't know Ruby well enough to know if these are commonly used features, but the statement that there are no sigils is false.
