facts must be an array

[Grant McInnes]

Am I right in thinking that facts must be an array, rather than an
arbitrary type of object?

What makes you think that?
Pat.

I was looking at this method Pat (from facts.rb):

def value
if @fact_value.size == 1
@fact_value[0]
else
@fact_value
end
end

along with this comment:

# Facts are collections or recordsets created by the user

In my case I want to pass in a Range object, but since Range doesn't
have a size method it chokes here. I can get round this by adding a
size method to a custom range class, but that seems a bit grody, and
I"m not sure what the size check buys you. What's it for?
