generally take as an indication that if I touch it I may get burned. :-)

write one's own function to do something similar. (If you do write your own,
it's may be best to write it as a Mixin that can be included (or patched)
into qx.core.Assert... then again, I seem to recall that statics from Mixins
don't get applied, but maybe I'm mis-remembering.

See, if every little detail was documented, you'd never have known that. :-)
