I didn't know this. I never noticed it, but all examples I used to learn 
from do indeed use Constants.

row=Struct.new(:street,:house)
d=[]
d<<row.new("Baker street", "14b")
d<<row.new("Sesame street","nope") # this should be in a loop
puts d[0].house

So changing "row" to "Row" is better?

a=Struct.new(:s,:o)
A=Struct.new(:s,:o)
puts a.new(1,2).class
puts A.new(1,2).class

=>#<Class:0x2c27534>
  A

Hmm. "A" is a full blown Class (as Robert wrote), and  "a" is reference 
to an anonimous Class, provided by Ruby to aid clumsy programmers?
I have probably some cleaning up to do tomorrow.

Thank you,

Siep
