Your code is equivalent to ...

b = puts 'I like Ruby'
puts b

... and produces the same results, which is nil because puts always  
returns nil. Eval returns whatever object comes out of its  
evaluation, which can be any kind of an object. You can't count on it  
returning a  string.

Exactly what are you trying to capture into a string?
