Hi,
Here are some ideas come up when writing some associative mapping algorithm/views. I think it'd be nice to have: * Auxiliary function 'eval' to force the evaluation of transform-like view e.g. fusion::eval(fusion::transform(a, b, some_void_return_ftor))
How's that any different from as_vector, as_list, etc. ? Also, what will be the container type of the result of "eval" ?
* Conversion function 'as_view' to make Container a view to reserve the mutability.
You mean to make it immutable?
What do you think? Are these already achieved in some way that I didn't aware of?
BTW, I just implemented left_mapping/left_mapped_view, it's used like
result = left_mapping(m1, m2, transform);
For elements not mapped, fusion::void_ is passed to transform.
Still mapping & full_mapping to do...
Awesome! Looking forward to this. Regards, -- Joel de Guzman http://www.boostpro.com http://boost-spirit.com
