Deprecating things without a replacement

[Robert Clipsham]

I've just begun updating my code to work with 2.054 and noticed that 
quite a few things have been deprecated - some without a decent 
replacement. Could the phobos team not make a habit of this please?

Example:

Before:
----
foreach (file; listDir(".", "*.d") ~ listDir("./foo/", "*.c"))
{
     // Do something
}
----
After (sorry about the awkward indentation):
----
void doSomething(string file)
{
     // Do something
}
foreach (string file;
              filter!`endsWith(a.name,".d"))`(
                         dirEntries(".",SpanMode.depth))
{
    doSomething(file);
}

foreach (string file;
              filter!`endsWith(a.name,".c")`(
                         dirEntries("./foo/",SpanMode.depth))
{
    doSomething(file);
}
----
Also note that you can't use dirEntries() ~ dirEntries() or 
chain(dirEntries(), dirEntries()) as DirIterator is not a range.

If things in phobos are going to be deprecated, could you make sure that 
a decent replacement for *all* use cases is in place before hand?

It would also be nice to add into the documentation how to use the 
replacement functions to the same effect - it took me forever to figure 
out how to replace listDir with dirEntries.
