These are probably not helpful:

irb(main):012:0>   c.instance_eval{ p send(:meth) }
42
=> nil
irb(main):013:0>   c.instance_eval " p meth "
42
=> nil

The strange thing is that s/protected/private/ avoids the error:

irb(main):014:0> class C
irb(main):015:1> private
irb(main):016:1> def m2; 43; end
irb(main):017:1> end
=> nil
irb(main):018:0>   c.instance_eval{ p m2 }
43

(ruby-1.8.2, anyway)

The original error (in the protected case) seem uncalled for....
