Weird, looks like there still is a stream module in the standard
library... This should be easily fixyble by replacing std.stream with
undead.stream in
https://anonscm.debian.org/git/debian-med/sambamba.git/tree/sambamba/slice.d#n31

Judging from how upstream's code looks, they should really make a new
release (since this particular issue is fixed there).
