How so? Anyway, what Walter said was not accurate. Languages are 
usually defined in a way where compile-time optimizations are 
optional and an implementation detail. Compile time evaluation of 
functions is nothing new, and a common optimization.

Because pow may be system specific at runtime. A compile time 
optimization should not lead to a different outcome.
