Re: is it bug? for

Dear Chung Chung,

no it's not a bug. The error message you get means that
there is no method "to_s" defined that will turn a String
into an Array.
You can change that by writing it:

class String
def to_a
return [self]
end
end

a="a string"
p a.to_a =>["a string"]


or simply by putting brackets around whatever
String you have.

Best regards,

Axel
