I will convert a Java program into D. The original Java code is
based on the class RandomeAccessFile which essentially defines a
set of methods for read/write Int/Long/Float/String etc. The
module std.stream seems to be a good fit for this job, but in its
documentation, it is marked deprecated.

is it safe to call `GC.removeRange` in dtor? i believe it should be safe,
so one can perform various cleanups, but documentation says nothing about
guarantees.

To turn it into an array, write:
aa.byKeyValue().array.sort!"a.key
How do I iterate through an AA sorted by key?
I am unable to .dup the aa.byKeyValue().
I have tried both
foreach(e; aa.byKeyValue().sort!"a.key < b.key")
{
//... use e. key && e.value
}
and
foreach(k,v; aa.byKeyValue().sort!"a.key < b.key")
{
}
i get :
