writefln() expects a format string as its first argument, not a uint. To print
a value without using a format string, use writeln().

reopening and turning into an enhancement request.  The writefln templates
could do considerably better about messaging the problem.

Yah, I changed things such that now you'll see:

/home/andrei/code/dmd/phobos/std/stdio.d(512): Error: static assert  "You must
pass a formatting string as the first argument to writef or writefln. If no
formatting is needed, you may want to use write."
