I wouldn't expect there to be any. eval or instance_eval with a string 
just parses and runs Ruby code, so the proper usage is "just put some 
valid Ruby code in there" :-)

That's why it's useful to use puts for debugging - you can see at a 
glance whether that code would be valid or not, if you had just inserted 
it into your program at that point.

No problem, glad it's all making sense.

Cheers,

Brian.
