What is your definition of a dangling pointer?
In the shown example we have a reference to a piece of memory
containing 'x', so this memory is not freed, it's used by the
program.

How do you do that in D? immutable everywhere?
for example:
foreach(Field field; fields) {
immutable string htmlOutputfile =

That does not use the -I switch.
