Besides, that is not what it said on the page. It said that 0^0 
may lead to a domain error. Which is reasonable for implementors, 
but it also referred to IEC60559 which set x^0 to 1.0 even if the 
base is NaN.

The goal of ISO standards is to codify and streamline existing 
practices for better interoperability, C++ is an ISO standard.
