Yeah, several threads got mixed with the "dot notation" one. That's OK.
DotNotation.thread = "What we think about Math Ed" # etc.
What I'm saying is we are culturally straitjacketed by words like "computer
science" which is actually today's major mainline math. Industry is using
dot notation to control the world (the e-World, just virtual) and K-12
stays ignorant because why? Because "dot notation" is not a math
notation. Says who? Says no one with a coherent bone in her/his body.
But then lots of people are spineless.
