Is there a reason why `deepCopy` doesn't exist on `--gc:arc` / is there a
workaround that works on the normal `gc` and `arc`? I don't think I see it
mentioned on your todo list above.
when hasAlloc and notJSnotNims and not usesDestructors:
# XXX how to implement 'deepCopy' is an open problem.
proc deepCopy*[T](x: var T, y: T) {.noSideEffect, magic: "DeepCopy".} =
## Performs a deep copy of `y` and copies it into `x`.
##
## This is also used by the code generator
## for the implementation of ``spawn``.
discard
proc deepCopy*[T](y: T): T =
## Convenience wrapper around `deepCopy` overload.
deepCopy(result, y)
