This issue was originally filed by @ahmetaa

A minor, and possibly breaking "familiarity" principle feature request.
Could it be possible to add Python's power (**) operator for representing Math.power(x,y)? Such as, x**y = Math.pow(x,y)

When this is implemented, make sure to make exponentials into compile time constants. Right now pow(.5,32) is not a compile time constant. Since shifts are currently broken in dart2js for large numbers I'm resorting to multiplications instead and it really makes the code ugly that I have to pre-compute the numbers.

I don't think an extra operator that is only really useful for numbers, is worth the syntactic footprint it requires.
A function like power could just become a member on num, so you could do 4.pow(5). Having it as external, and still working on both doubles and integers, seems unnecessary.
