Guys, seriously this bug has been fixed for quite some time:
https://issues.dlang.org/show_bug.cgi?id=8838
https://issues.dlang.org/show_bug.cgi?id=12625
https://github.com/dlang/dmd/pull/5972

Why don't you use -dip1000???

/home/zombinedev/dlang/dmd-2.073.2/linux/bin64/../../src/phobos/std/stdio.d(3439): Error: template std.stdio.File.LockingTextWriter.put cannot deduce function from argument types !()(string), candidates are:
/home/zombinedev/dlang/dmd-2.073.2/linux/bin64/../../src/phobos/std/stdio.d(2643):        std.stdio.File.LockingTextWriter.put(A)(A writeme) if (is(ElementType!A : const(dchar)) && isInputRange!A && !isInfinite!A)
/home/zombinedev/dlang/dmd-2.073.2/linux/bin64/../../src/phobos/std/stdio.d(2672):        std.stdio.File.LockingTextWriter.put(C)(C c) if (is(C : const(dchar)))
scope_test.d(5): Error: template instance 
std.stdio.writeln!string error instantiating
scope_test.d(11): Error: scope variable ans may not be returned

The only issue is that not enough people (except Walter & Andrei) 
are interested in pushing -dip1000 as the default. Druntime 
already compiles with -dip1000, so Phobos is the next frontier.
