Small optimizations? Did you check that idiot checkbox yet?

I started to write the following code:

operationsInTransactions.GetOrAdd(txId,  new List<Command>())
    .Add(new Command
    {
        Key = key,
        Position = position,
        Type = CommandType.Put
    });

But then I realized that in the happy path, I would always allocate a list, even if I don’t need it, and I changed it to this:

operationsInTransactions.GetOrAdd(txId, guid => new List<Command>())
    .Add(new Command
    {
        Key = key,
        Position = position,
        Type = CommandType.Put
    });

Why am I being stupid?

Hint: It has nothing to do with the stupidity associated with trying to do micro optimizations…
