[omaha] Tutorial: Keyword Arguments

[Jeff Hinrichs - DM&T]

because the language rules allow things like this:

def parrot(	voltage,
			state='a stiff',
			action='voom',
			type='NorwegianBlue'):
    print "-- This parrot wouldn't", action,
    print "if you put", voltage, "volts through it."
    print "-- Lovely plumage, the", type
    print "-- It's", state, "!"

Now you may be correct that you could infer without it, I've never
seen a discussion that talks about dropping the colon.  However, I
would bet that GvR has considered it and decided that it is
problematic without it.  However, the colon is a part of the language
definition.
