I thought this might be the answer. It's clearly too much to ask of  
all lambda-coders and would-be lambda-coders in the world.

My two cents, perhaps I'm wrong and the Schemers and others will  
switch their kbd configs. Or the code generators will rise and  
exterminate lambda-coding humans. But I doubt it.
