#6268: Conflict between fusion and phoenix operator<
---------------------------------------------------+------------------------
Reporter: Nathan Ridge <zeratul976@…> | Owner: theller
Type: Bugs | Status: new
Milestone: To Be Determined | Component: phoenix
Version: Boost Development Trunk | Severity: Problem

---------------------------------------------------+------------------------
When using the sequence_facade extension mechanism to adapt my own Fusion
sequences, I experience a conflict between fusion and phoenix's operator<.
The problem is that in a lambda expression like "arg1 < s" where "s" is a
Fusion sequence defined using sequence_facade, Fusion tries to instantiate
its operator<, but the instantiation gives an error because "arg1" is not
a Fusion sequence and does not have "size" etc.
Here is a minimal sample that reproduces the problem:
#include <boost/fusion/sequence/comparison.hpp>
#include <boost/fusion/sequence/sequence_facade.hpp>
#include <boost/phoenix/core.hpp>
#include <boost/phoenix/operator/comparison.hpp>
struct foo : boost::fusion::sequence_facade<foo,
boost::fusion::random_access_traversal_tag>
{
// Rest of the sequence_facade extension mechanism code omitted,
// as it is not needed to reproduce the error
foo() : x(), y() {}
int x;
int y;
};
int main()
{
auto x = boost::phoenix::arg_names::arg1 < foo();
}
Here are the errors:
