Two things off the top of my head:

1.  std.stream doesn't correctly support files > 2GB on 32-bit Linux, and possibly
on other OS's as well.

2.  It doesn't have a range interface.  I can't tell you how useful something like
this is to me:

filter!"a.length > 0"(
    map!strip(
        File(myFilename).byLine()
    )
);

That said, please don't use Java as a reference for how to design a stream API.
It just seems horribly verbose when trying to do something simple.
