You might look into list comprehensions. You could probably do this
with two of them:

<code>
# completely untested
lMandatory = [arg for arg in cls.dArguments if arg is True]
lOptional  = [arg for arg in cls.dArguments if arg is False]
</code>

Something like that. I'm not the best with list comprehensions, so I
may have the syntax just slightly off. See the following links for
more information:
