I was just working on this, for the same reason: All the lambdas
threaten to make the code unreadable, and hard to maintain (as so many
of them declare the same function). But what we can do is:
// Takes the argument d and returns a (pointer to a) function that
returns whether
// some Branch b has the name d.
std::function<bool (Branch const &)> BranchNamesEqual(docstring const & d)
{
return [d](Branch const & b){ return b.branch() == d; };
}
I think that should work in C++11? Similarly in other cases.
I'm happy to do these fixes if the idea seems right.
