Solve the following python programming problem given the following code:
def add_parser_method(name, * _specs) : 
    if (name in CACHE) : 
        (otherspec, checker) = CACHE [name] 
        assert (otherspec == _specs) 
        return checker 
else : 
        specs = unroll.unrolling_iterable (map (make_spec, otherspec)) 
        def checker(self) : 
            arg = self.next () 
            for spec in specs : 
                if spec.conforms (arg) : 
                    return arg 
raise_error (self, arg) 
checker.__name__ = name 
        def raise_error(self, arg) : 
            names = ' '.join ([spec.repr () for spec in specs]) 
            if (len (_specs) == 1) : 
                types = names [0] 
else : 
                types = ('(or/c %s)' % names) 
msg = ('%s: expected %s at argument %d got %s' % (self.context, types, self.index, arg.tostring ())) 
            raise SchemeException (msg) 
@ jit.unroll_safe 
        def _checker(self) : 
            length = (len (self.args) - self.index) 
            results = ([None] * length) 
            for i in range (length) : 
                results [i] = checker (self) 
return results 
CACHE [name] = (_specs, checker) 
    setattr (ArgParser, name, checker) 
    setattr (ArgParser, ('_' + name), _checker) 
    return checker 

    
    

    Fix the buggy line: specs = unroll.unrolling_iterable (map (make_spec, otherspec))

#Here is Python program to fix the buggy line: specs = unroll.
