The attached code should print "hello 99"; instead
it prints other number. It looks as if the reflect
package isn't returning a correctly curried method function value.

Comment 2:

You are asking reflect to do something that Go the language does not:
give you a curried method for the expression x.Foo.  
I will make Interface panic in this case for now.  We can revisit it
once x.Foo is valid Go.  I don't want to be in a position where reflect
is being used to circumvent shortcomings in the language itself.

Status changed to LongTerm.
