Nested functions that allocate their environment dynamically can be

the data needed into an anonymous struct that copies the state inside,

I wonder how to integrate that within the language nicely.
Some of us were discussing this at dconf. Essentially, we need a way to
create a functor similar to how C++ lambdas do. The most straightforward
way would involve string mixins, and you'd do something like
auto f = makeFunctor!"function code here"(arguments);
Which could look like this with AST macros ;)
auto f = makeFunctor(args) {
function code goes here, no strings are needed
}
