You have to end your input with ctrl-D.  DMD is not a REPL so it's not
going to evaluate individual input lines immediately.

But anyway, this particular one is a joke that refers to one of the
winning entries of the IOCCC from 1988 (see the entry by spinellis),
consisting of the single line:

	#include "/dev/tty"

It probably no longer works on modern C compilers, but the intent ought
to be obvious. :-)
