Great, thanks Nick. I have however found a few other issues.

Using this code:

	auto connection = new Connection(MySQLSocketType.phobos, 
"127.0.0.1", "root", "r00t", "Project");
	auto command    = new Command(connection, "INSERT INTO tblUser 
(name, age) VALUES (?, ?)");
	command.prepare();

	ulong rowsAffected;
	string name;

	foreach (int age; 0..100000)
	{
		name = "Test User";
		command.bindParameter(name, 0);
		command.bindParameter(age, 1);
		command.execPrepared(rowsAffected);
	}

Raises two simple to fix errors in the connection code.

1). mysql/connection.d(3845): Error: more initializers than 
fields (5) of ParameterSpecialization

Basically the initialisation of the structure contains too many 
parameters.

2). mysql/connection.d(3858): Error: no property 'dummy' for type 
'ParameterSpecialization'

The structure doesn't contain a 'dummy' property. Debug info i 
guess?
