Well, you can't because pow() is not known at compile time (in a 
portable way). It is only known, in the general case, when 
executed. If you allow it to be evaluated at compile time you 
risk a compiletime pow(x,y) value to be different from a runtime 
pow(x,y) value even though the parameters are exactly the same. 
Which could lead to bugs (like comparing for equality).
