Hi Sebastian,

Hmmm...... I think I know what the problem is ...
Foo::get is const

struct Foo{
   std::string get() const { ... }
};

So it is not a good candidate to use in string::replace.
I wonder how I can work around it, since I want to transform a _copy_ of that.
Is there a way to create a copy on the fly? something like:
...bind(rep, std::string(bind(&Foo::get, _1)), 0, 5, ""));

Thanks again for your insights.
Kobi.

Hmmm ... the <unknown type> is suspicious. The problem might be that
&std::string::replace is ambiguous, as it is overloaded. Try this:

std::string & (std::string::*rep)(std::string::size_type,
std::string::size_type, const char *) = &std::string::replace;
std::transform(array.begin(), array.end(), std::back_inserter(tr),
  bind(rep, bind(&Foo::get, _1), 0, 5, ""));
