ok, but I wasn't explaining concurrency to you. If you're referring to the paragraph about the cars, I was explaining why your answer was incorrect. I was not explaining concurrency. If you're referring to my comments about the map (following my "Please clarify....." statement), I was simply setting up the scenario I was facing and was asking for clarification as to where I may have made a mistake. I was, again, not explaining concurrency to you. > For a map access, if you hold the lock for as few instructions as > possible, it shouldn't hurt much. > You either didn't understand the paragraph about the cars or you didn't read it. Much of what I wrote was explaining why this isn't necessarily the case. In my case, running goroutines to avoid users blocking each other and then setting up a bottleneck undermines the point in using goroutines because they all have to wait for each other anyway to complete their goroutines. > If you're after an idea of the best solution, that will be harser - maybe > not a map is the best answer for your specific use case, but a slice.

As far as I know, the only structure in golang that allows one to use a string as a key would be a map. > If you can write down the access to the innermost element of your > multidimensional map as m[a][b][c][d], then you know that you won't have > more than four levels, so you can use a map[[4]string]string. > I spent about an hour or two trying to get this suggestion to work.

I was under the impression that Golang has strictly defined equality. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
