That really should be too, but work is probably going to have to be done to make sure that format and std.conv.to can be pure, since they're pretty much required in most toString functions. I believe that changes to toUTF8, toUTF16, and toUTF32 were made recently which are at least a major step in that direction for std.conv.to (since it uses them) and may outright make it so that it can be pure now (I'm not sure if anything else is preventing them from being pure). But I have no idea what the current state of format is with regards to purity, and if the changes to toUTFx weren't enough to make std.conv.to pure for strings, then more will need to be done there as well. - Jonathan M Davis
