cdarke has asked for the wisdom of the Perl Monks concerning the following question:
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?
Global variables and contextual variables have been unified to both use the * twigil. I'll look into updating the Differences document (which usually lags behind the synopsis documents). (Update: I removed the mention of + in the svn, it'll take at most an hour until the HTML version shows up correctly).
For better resources on Perl 6 I recommend following the links on http://perl6-projects.org/, especially the blogs. I admit it's a bit hard to see how up-to-date the individual pages are.
