global name 'self' is not defined - noob trying to learn

[mark.seagoe at gmail.com]

Hi.  So now I have this class that works to allow me to pass in my
reg_info struct.  However when I try to make it part of my class it
gets an error "global name 'self' is not defined.  I've never seen
this error before.  If I comment out the line below 'self.reg_info =
reg_info" then the code runs... but I need to add stuff to this class,
and so I'm wondering why I can't use 'self' anymore?

from ctypes import Structure, c_byte, c_char

class REG_INFO(Structure):
    _fields_ = [
        ('address', c_byte),
        ('message', c_char * 256)
        ]

class myclass(long):
    def __new__(class_, init_val, reg_info):
        print reg_info.message
        self.reg_info = reg_info # <== Offending line
        return long.__new__(class_, init_val)

#
# setup
my_reg = REG_INFO()
my_reg.address = 0xab
my_reg.message = 'hello world'

print 'TEST 1'
dog = 0x123456789ABCDEF0
print 'type(dog) = %s' % type(dog)
print 'dog val = 0x%016X' % dog

print 'TEST 2'
cat = myclass(0x55, my_reg)
print 'cat val = 0x%016X' % cat
print 'type(cat) = %s' % type(cat)

Thanks!
