I disagree, we have a reference to a `tuple` not a
module level constant.

     # module level constant
     from myhdl import *
     MAX_LEVELS = 4

     # reference to a tuple
     coef = (1,2,3,4)

Module-level constants are fairly rare.  The python
documentation [1] does not use cap names for references
to tuples (can't say I have seen other that does)
