[C++-sig] Boost.Python and std::string subclassing

[Pertti Kellomäki]

The library I am wrapping creates a subclass TCEString of std::string.
Py++ generates me bindings for the subclass, but in Python the
subclass does not quite work like std::string. For example,
the Python expression

"%s.%s.%s" % (term.functionUnit().name(), term.port().name(), 
term.operation().name())

returns the string

"universal_fu.OCSetting32.<TCE.tools.TCEString object at 0x81308ec>"

because term.operation().name() returns a TCEString instead of std::string.

Is there some convenient way to make the subclass work like std::string?
I know how to do it by defining a __str__ method in the Python class,
but I am hoping that there might be a simpler way to do it using
Boost.Python or Py++.
