141 # There used to be a claim that it simplified debugging. There may have

144 # however, there is no debugging gain, and in fact frequent debugging *LOSS*,
145 # since many debuggers don't handle unions very well, and usually there is
146 # no way to directly specify a union from a debugging prompt.
147
148 # Furthermore, release builds should *NOT* be done this way because (a) you
149 # may get less efficiency, with compilers that can't figure out how to
150 # optimize the union into a machine word; (b) even worse, the union type
151 # often triggers compiler bugs, especially when combined with Mule and

153 # *AND CURRENTLY HAPPENS WITH VC++*, at least when using pdump. Therefore,
