If the compile-time parameter was of the downcast type ICM, then the IMCM parameter method would not be called. Thanks Rob for setting me straight. :)

Cedric’s sample makes a runtime check for an inheritance relationship between ICM and IMCM, whereas I presume the relationship at compile time. It is something I should know at compile time. I compile based on the knowledge of inheritance relationships all the time. Either way, its a dreadfully smelly sample. I like your assertion of the Ask-Don’t-Tell principle.

As a coffee aficionado I also whole-heartedly approve of the milk-first (water-last) principle. :)
