We can only make it work if you accept al= ways getting an OpenStruct in return

Hmm= . That doesn't seem to work for me in 1.8.7 or 1.9.2

ruby-1.9.2-p290 :001 > class OpenStruct

NoMethodError: undefined method `foo' for #<OpenStruct:0x000001= 00a9c3a0>
from (i= rb):3:in `method_missing'
from (irb):7

from /Users/peterhickman/= .rvm/rubies/ruby-1.9.2-p290/bin/irb:16:in `<main>'

Same error in both
=A0

Just to be sure: yo= u did require "ostruct" did you?

robert@fuss= el:~$ irb -r ostruct
