I think it may be best to introduce a new array property:
dest.slength = src.length; // same as dest.length = src.length, but
follows D1 rules (slength = stomp length)
If you use slicing (I'm assuming you do), then appending would have to
become a function/member instead of ~=.
I can help write those if you want.
Eventually the D1 legacy will go away, so probably it's better to
introduce something that later can be removed safely. So instead of
"slength" it's better a name like "__slength", to allow its usage only
if you compile with the "-d" compile switch (that activates deprecated
features) and instead of a built-in array property as "length" it could
be better (if possible) to make it a function in the object module as
assumeSafeAppend.
I hope you understand that I was not recommending adding this to druntime
or phobos. This is not a typical requirement.
Anyone starting with D2 code would use something other than straight
array-slices to do this kind of work.
