Compilers had done to death figuring out how best to optimize what
the developer wrote. The future is optimizing what they intended to write.

A while back I had the idea of trying to figure out what floating-point
calculation was being attempted, e.g., using a Taylor series when a Chebyshev
series would be more efficient.

I'm sorry to hear this news about Walter.
