super w/ implicit arguments in Ruby 1.9

[Intransition]

Hi--

Debugging a library for 1.9.1 compatibility. I get this error:

6) Error:
test_02_002(TC_Inheritor_02):
RuntimeError: implicit argument passing of super from method defined
by define_method() is not supported. Specify all arguments
explicitly.

The offending code is:

define_method( key ) do
defined?(super) ? super.__send__(op,obj) : obj.dup
end

So I'm confused since I am not calling super without arguments, though
I am asking if it is defined. But #defined? works in a special way so
as not to actually invoke it's argument, right? Or is it something to
with __send__? What is amiss here?

Thanks.

read the line like the parser will:

defined?(super) ? (super).__send__((op),(obj)) : (obj).dup

the object that gets __send__ is the return value of super. Can you
try:
defined?(super) ? super().__send__(op,obj) : obj.dup
so that the implicit args of super aren't an issue? (because you
explicitly give an empty arg list)

read the line like the parser will:

=A0 =A0defined?(super) ? (super).__send__((op),(obj)) : (obj).dup

the object that gets __send__ is the return value of super. =A0Can you = =A0
try:
=A0 =A0defined?(super) ? super().__send__(op,obj) : obj.dup
so that the implicit args of super aren't an issue? (because you =A0
explicitly give an empty arg list)

Doh. I should have seen that. Thank you for helping my poor little
overtaxed brain

Unfortunately now I get:

3) Error:
test_02_002(TC_Inheritor_02):
NoMethodError: super: no superclass method `koko' for

`block (2 levels) in inheritor'
/mnt/repos/rubyworks/facets/test/more/test_inheritor.rb:31:in
`test_02_002'

Does defined?(super) not work in 1.9? If so, how does one work around?

No, it works. I checked. So it's something else.

Thanks for the help.
