Because colour is not a module, it is a record. Sorry, I assumed that
people would be familiar with Pascal records (similar to C structs) and
it wouldn't need explanation. My bad :-(
The closest example in Python would be:
def class Colour:
def __init__(self, blue=0, green=0, red=0):
self.blue = blue
self.green = green
self.red = red
which would become something like:
def class Colour:
def __init__(self, blue=0, green=0, red=0):
# pseudo-Python code borrowing concept "with" from Pascal
with self:
blue = blue
green = green
red = red
And now you can see why Python doesn't support this idiom.
