The function rewrite should really be targeting `core.math` instead of
`std.math`.

Or, granted that this is an operation with a special syntax, the initial
template could be part of object.d, which then forwards to the correct function
as appropriate.

  Can we have ^^ rewritten into a simple pow?
 
 Note: I think that currently a^^b is optimized in some special cases by the
 compiler (like b = 2). A simple function call causes a loss of those handy
 optimizations.

I never asked for those optimizations to be disabled. I am solely talking about
the cases when ^^ is rewritten as a function.

An even better idea occurred to me today, now that UFCS has been introduced.
Instead of my original proposal, why not do this:

a^^b

turns into

a.pow(b)

Due to the way properties are looked up this is safer than the original
proposal (bad things won't happen if you have variables named 'pow' for
example).
