parse!enum(string) must look for a longer match.

--------------------
import std.conv;
unittest
{
    enum E { aa, aaZ, aaaZ }
    assert(to!E("aaaZ") == E.aaaZ);
}
void main() {}
--------------------
% dmd -unittest -run test
std.conv.ConvError: std.conv(684): Can't convert value `Z' of type
const(char)[] to type E
