Hi,

FWIW, it seems to be broken since 1.8.3.

$ ruby -ve 'Struct.new(:valid?).new.valid?'
ruby 1.8.3 (2005-09-21) [x86_64-linux]
-e:1: undefined method `valid?' for #<struct #<Class:0x2aaaab3e8160>
:"valid?"=nil> (NoMethodError)

I couldn't find any mention about this behavior both in [1.8.3 changes][1]
and [1.8.4 changes][2].
