There will be an LL/Phx merger. I hope it will be soon. That depends a lot on which is the least compiler to support. Right now, I have the core up and running on VC7 but ICEs on VC6. Either I leave VC6 behind (now that 7.1 is imminent), or I spend more time hunting by trial and error. The new LL/Phx merger is MPL based. BTW, Borland works as it does in Phoenix as do a lot more compilers: http://spirit.sourceforge.net/wiki/index.php?page=Compiler+Table So the question is *to-vc6-or-not-to-vc6*, please send in your votes. > Second question: I'm trying to do something which I > think could be done with some of the functional programming > libraries and tools available here at boost, perhaps > in combination with other tools from elsewhere. [snip] Ah..Lazy-evaluation... This was asked in the past. Phoenix named placeholders: Phoenix+boost::function :-)... This link might be of interest to you: http://article.gmane.org/gmane.comp.parsers.spirit.general/3393/match=placeholder+cpp This feature will hopefully, if Jaakko agrees, be part of the new merger. I'm heavily investigating *true* lazy evaluation, not to be confused with partial evaluation that's currently done in LL and Phoenix. To avoid confusion, I should change everything "lazy" in the Phx docs to probably be "deferred". These are subtly different concepts. -- Joel de Guzman joel at boost-consulting.com http://www.boost-consulting.com http://spirit.sf.net _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
