And so you have managed to separate one set of looping conditions into two 
parts. What is the significance of the name “styles”? None at all. What 
purpose does it serve? None, really. Does it ease the maintenance burden? 
No, but by splitting your attention across two places, it actually adds to 
it.

Here’s another example for you to chew on:

    for \
        name, reg, doindir \
    in \
        (
            ("R0", 0, True),
            ("R1", 1, True),
            ("R2", 2, True),
            ("R3", 3, True),
            ("R4", 4, True),
            ("R5", 5, True),
            ("R6", 6, True),
            ("SP", 6, True),
            ("R7", 7, False),
            ("PC", 7, False),
        ) \
    :
        ...
    #end for
