Dear All, 

Does anyone know any way to directly pass a lambda as a functor to an interpolation function? 

For example, the signature of the linear interpolation function:

template < class ForwardIterator, class Functor>
typename Functor::result_type::first_type
linear_interpolation(ForwardIterator first, ForwardIterator beyond,
                     const typename
                       std::iterator_traits<ForwardIterator>::value_type::
                       second_type& norm,
                     Functor function_value)

requires Functor to provide a type Functor::result_type. This makes it impossible to pass a raw lambda.

Of course one could wrap the lambda with e.g. std::function, but in many cases this is not optimal performance-wise nor style-wise.  

Is there any other way to pass a raw lambda that I am not aware of?

If not, are there any plans to support lambdas in future releases?

Best,

Panos
