I have the following code, which used to work under IronRuby 0.9.1 and  
earlier

class Object  
def method\_missing(sym, \*args, &block)  
if sym.to\_s =~ /blah regex/  
# do stuff  
else  
super # call through to underlying ruby method\_missing  
end  
end  
end

Under 0.9.1 this worked across the board, and under 0.9.2 it works for  
most  
objects, but suddenly for COM objects it’s throwing an exception on the  
call  
to ‘super’

Repro code:

load\_assembly “microsoft.office.interop.word”  
word = Microsoft.Office.Interop.Word.ApplicationClass.new  
word.fdsfgdsf  
System::NotSupportedException: super(.S,1\*&):482 @1 not supported on  
foreign  
meta-objects  
from (irb):12:in `method_missing' from (irb):16 from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:150:in`eval\_input’  
from :0:in `eval' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:263:in`signal\_status’  
from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:147:in `eval_input' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:146:in`eval\_input’  
from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:70:in `start' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:69:in`start’  
from C:/Dev/TEST/ruby/bin/iirb:13  
from :0:in `loop' from :0:in`catch’  
from :0:in `catch’

I’d be more than happy to work around it by not calling super if the  
object  
is a “foreign meta-object”, but how can I tell that?
