yes, but you are using ref : "auto let(Ts...)(ref Ts vars)"
so vars are changed, no need to store anything, no?
i was wondering if there is some subtleties or efficiency
reasons for using pointers
Thanks for the code!
Yep, this way it works too, by capturing input vars in a closure.
So the main difference is that your variant allocates GC memory
while original variant does not allocate anything in the heap
(only on stack).
