[C++-sig] [Py++] free operators

[Michał Nowotka]

Hello,
I want to expose to python following code:

typedef std::map<const Haplotype*,double> ProbHaplotype;

typedef std::map<const Fenotype*,double> ProbFenotype;

typedef std::map<const Genotype*,double> ProbGenotype;

(...)

std::ostream& operator<<(std::ostream& os, const ProbHaplotype& hapl);

std::ostream& operator<<(std::ostream& os, const ProbFenotype& fen);

std::ostream& operator<<(std::ostream& os, const ProbGenotype& gen);

but I get some warnings:

WARNING: extern std::ostream & hapl::operator<<(std::ostream & os,
hapl::ProbGenotype const & gen) [free operator]
> warning W1052: Py++ will not expose free operator "extern std::ostream & hapl::operator<<(std::ostream & os, hapl::ProbGenotype const & gen) [free

How can I get rid of it?
