This gives differences between Perl 5 and Perl 6.
Under "Global variables have a twigil" it says:
"for contextual variables, it's +."
An example follows using $+, which works for me in pugs.
There is a link to "Names and Variables" in S02, where there is a list of twigils.
The + is not in that list. So, is + a twigil or not? If so, what is its meaning?

Or maybe it is no longer used?
