// Alan's editorializing:
                //   I think the candela is a scam, and I am completely
                //   opposed to it.  Some good-for-nothing lighting "engineers"
                //   or psychologists probably got this perceptually-rigged
                //   abomination into the whole otherwise scientific endeavor.
                //
                //   What an unbelievably useless and stupid unit.  Is light
                //   at 540.00000001 x 10^12 Hz (or any other frequency) zero
                //   candela?  Is this expected to be an impulse function at
                //   this frequency?  Oh, wait, the Heisenberg Uncertainty
                //   Principle makes this impossible.  No mention for
                //   correction (ideally along the blackbody curve) for other
                //   wavelengths?  Damn you, 16th CGPM!  Damn you all to hell!
