I want to erase items in a map based on some criteria.

use standard library:

std::remove_if
(connectionMap.begin(),connectionMap.end(),ConnExpired(current));

remove_if won't work on a map. It requires that elements of a container
be assignable, and map's elements aren't. Try it, it won't compile.

I did and got nervous a bit.Looks like we have to write the code
manually.But I do not see any reason for assifnability.Maybe remove_if
needs to be changed to what we did here?
