[Newbies] >> notation

[Ron Teitelbaum]

You will also sometimes see something like:

Person class >> new

When someone is writing about code.  This means that you should look on the
class side of Person for the method #new.  People will also indicate the
method name with a symbol (for example #new) if they are writing the method
name in-lined in a sentence.
