The const-by-default lambdas are the black swans of C++.

The fit documentation should at least provide a design rationale for
its const-by-default decision which is addressed at those who are
unfamiliar with the virtues of immutability.

Another concern with fit::mutable_ is its name. As you have already gone
down the type-traits naming path with fit::decay, it may be an idea to
rename fit::mutable_ to fit::remove_const.
