Yes,
- Tokenish is a class variable of String, while #tokenish is a method of 
Character
- Tokenish is initialized based on what #tokenish returns
- $~ would return true, but it's not tokenish
- performance (though something like this could work if we had access to 
Tokenish: ^(Tokenish at: value + 1) == self and: [ self ~~ $~ ], but see 
below)
- Tokenish doesn't work with WideCharacters
