Summary: Documentation for String.scan has a bad example.

Initial Comment:
The documentation for String.scan says -

And the block form:

        a.scan(/\w+/) {|w| print "<<#{w}>> " }
        print "\n"
        a.scan(/(.)(.)/) {|a,b| print b, a }
        print "\n"

     _produces:_

        <<cruel>> <<world>>
        rceu lowlr

In the statement 
a.scan(/(.)(.)/) {|a,b| print b, a }

the use of variable "a" inside the block confuses the novice.

Its a simple variable fix.

Thanks
