Yes, because you assigned to the global constant "Street" and did not 
define a method with that name.

See Siep's suggestion.  Of course it depends on how you want to work 
with the data but the most likely case is that you treat one set of 
street, house etc. as a single record so it makes sense to do it the way 
Siep suggested (probably using a constant for the Struct and not a local 
variable because Struct.new really defines a new class).
