hi all,

in this (http://pastie.caboo.se/97662 ) code :

module Kernel
def expected_argument_list
2
end

def before (name)
puts :hola
define_method(name){
if expected_argument_list==1
yield nly_one
else
yield ne,:two
end
}
end
end

class A
before :foo do |*args|
puts second
end

before :foo do |first , second|
puts second
end
end

a = A.new
a.foo

Does anyone know of a way to determine what argument list was
specified when the block is created?

i mean i want to implement the function expected_argument_list, to
return the length of the argument list that the block expected.
Probably is not possible to do that

When are defined the variables of the block, in the class definition
time, or after the yield call?

Thanks
