12:42 :: jhass:: guinsly: is that your real code? or an example that reproduces? because class foo is invalid
12:43 :: shevy:: arup_r, http://stackoverflow.com/questions/543774/undef-why-would-you-want-to-undefine-a-method-in-ruby - but it seems as if people rarely need it
12:43 :: jhass:: also note that the @firstname outside a def is a different @firstname
12:43 :: jhass:: guinsly: ^
12:43 :: shevy:: I never needed undef, I did need undef_method (or actually... remove_method it was...)
12:43 :: guinsly:: jhass, this the realcode except class foo is name LoadFile
12:43 :: jhass:: why did you change it?
12:44 :: jhass:: but your issue is probably what I just said
12:44 :: apeiros:: weird indent. tabs mixed with spaces? o0
