Hi list,
Can we please put an end to this insane idiosyncrasy going on here lately? It doesn't lead to anywhere!
Ok, we get it ... people want to write local functions in the usual way.
Here is what I have to propose: Why not combine Boost.Local and Boost.Phoenix and keep everybody happy? If the macros provided by Boost.Local would emit some instance of a phoenix::function.
The macros provided by Boost.Local already generate PFOs. The goal of Phoenix should be to integrate seamlessly with PFOs, which are ubiquitous in C++. It shouldn't be required to make every type be a phoenix type to use it with phoenix. That is, currently, the main problem with phoenix: you need to adapt all functions before you can use them. I've already proposed the addition of a function named "lazy" (I think I suggested it during both the v2 and v3 reviews), that would be trivial to write, and that simply turns a PFO into a phoenix actor. That little thing would make Phoenix much more usable. Instead of BOOST_PHOENIX_ADAPT_FUNCTION(R, f_, f, N) /* ... */ void g() { /* ... */ my_higher_order_algorithm( f_(arg2, arg1) + arg3 ) } We could just write my_higher_order_algorithm( lazy(f)(arg2, arg1) + arg3 )
