This looks like an IRB anomaly:

10:43:19 [robert.klemme]: irbs
>> require 'ostruct'
=> true
>> x = OpenStruct.new
=> <OpenStruct>
>> p x.public_methods.select {|o| /^foo/ =~ o}
[]
=> nil
>> def foo() "buh!" end
=> nil
>> p x.public_methods.select {|o| /^foo/ =~ o}
["foo"]
=> nil
>> exit
10:43:29 [robert.klemme]: ruby /c/temp/ruby/ostruct-foo.rb
[]
[]
10:43:35 [robert.klemme]: cat /c/temp/ruby/ostruct-foo.rb
require 'ostruct'

x = OpenStruct.new
p x.public_methods.select {|o| /^foo/ =~ o}

def foo() "buh!" end

p x.public_methods.select {|o| /^foo/ =~ o}

Kind regards
