I really don't like macros.
Can you say why? I ask only because FOREACH doesn't suffer from many of the problems macros typically suffer from.
I have a hard time accepting boost PP but at least we have never before used macros in a way that means that they proliferate into user code.
I can not see why this has even come up for formal review.
Because a number of people have found it useful.
If this is auseful feature then surely it should be taken up as a core language feature.
FOREACH is useful /today/.
I would not have such a problem if we had an experimental track and then people could try ideas before making a proposal.
We do. It's called boost-sandbox. Many of the reviewers have been using FOREACH for a year or more. The code has been publically available in one form or another since 2003.
I am voting no on principle.
Fair enough. -- Eric Niebler Boost Consulting www.boost-consulting.com
