cat > enh.d << CODE
import std.format;
enum Op { lt, gt, eq }
void main()
{
auto s = format!"%s"(Op.lt);
Op op;
formattedRead!"%s"(s, op);
}
CODE
dmd -run enh.d
----
phobos/std/format.d(4872): Error: template std.format.unformatValueImpl cannot deduce function from argument types !(Op)(string, const(FormatSpec!char))
...
enh.d(7): instantiated from here: formattedRead!("%s", string, Op)
----
Formatting and unformatting should be symmetric, but currently (2.077.1) enums are not supported by unformatValue.

Just ran into this today (2.096.1).
Surprised this isn't fixed yet...
