Where is CASE?????

[Harry George]

No, but do you really need it?  First, if you do a performance
profiling, you will find if...elif...elif... is not so bad.  But it
isn't pretty either.  So consider using a map:

color_function={'red':do_red,'green':do_green,'blue':do_blue}
#get some case value in domain red,green,blue, then:
    ftn=color_function[value]
    ftn()

Or even:
    color_function[value]()

Further, this approach lends itself to dynamically defining and adding
cases, which can't be done with statically compiled CASE statements.
Thus registering new colors and their actions is a piece of cake.
