The << direction is correct (and intuitive IMHO), given:

class A < B
end

This can do two things, either creates and opens class A extending class 
B or reopens class A if it already exits (in the second case the 
superclass is optional, but if given it must match the existing class 
superclass)


now, given:

s = "some_string"

class << s
end

What this does ? it either creates and opens singleton class for s 
instance or reopens the singleton it if it already exits. Since 
singleton classes dont have their names you could also imagine 
<anonyous_name> between class and << tokens here.

The only question that could arise is: why there are two different 
tokens (<< and <) ?. I think Matz wanted to syntactically differentiate 
how to deal with classes and metaclasses.
