string_streamx is a string_stream with additional formatting options. Currently the only extra option is the ability to expand strings to a length using a fill character, along with left/right justification. More options similar to std::stringstream may be added in the future. These extra options do come at a performance cost, and string_stream should be preferred unless the extra options are absolutely needed.
