After some further digging in the code, "to_a" is used in a host
of contexts. Not just Model.find(), but things like
params[:blah].to_a.include?('some key string')
and a number of others.
I think I'll be needing both the assumed new behavior of
find(:all), and the Array() call.
I'm curious, where is this Array() method defined, and what
is it exactly? A method named like a class? Or am I actually
"invoking" the class in a method-ish way? Where might I
find documentation on this?
Thanks...
