WITCH: Revision 34
What Is This Character Here (WITCH)?
The Perl6 WITCH is mostly a bunch of hyperlinks that allows one to find documentation for operators, special variables and other features when there is a "mystery character" whose usage is not understood.
Start by clicking on the character you do not understand the usage of. You will be brought to a page that tells how the character is used and/or can point you to compound operators or other uses for the character.

In addition to a handy way to find out what an operator does, it also helps show how Perl 6 tries to allocate characters to uses that have similar or related semantics, by collecting a list of the various uses of a character in one place. Also mentioned are uses of characters from Perl5 and some other languages, so the index can also be used in a "how do I?" fashion.
