I'm not sure.

The purpose of Phoenix (and Lambda, and boost::bind) is simple: to provide a 
concise way to create function objects. Most C++ programmers are familiar 
with the need to write function objects and there is no need to learn SML to 
take advantage of the basics. Many people start with just needing *_1 < *_2 
or bind(&X::name, _1) < bind(&X::name, _2). Some of them simply do not need 
to go further (or aren't allowed to, by a coding standard).
