[julia-users] Why isn't typeof(Float64[]) <: typeof(Real[]) true?

[Patrick Foley]

Is there a way to get around this?  I have a lot of types (foo1, foo2, 
....) all of which are subtypes of an abstract (bar).  I want to be able to 
define the behavior for arrays of any of the foos just by defining the 
behavior of an array of 'bar's.  Any advice?
