The templates were removed without reimplementing from scratch: https://github.com/danielbot/Shardmap/blob/master/shardmap.h#L88 https://github.com/danielbot/Shardmap/blob/master/shardmap.cc#L82 The duopack/tripack facility, central to Shardmap efficient scalability, are now just ordinary C code that happens to be compiled by a C++ compiler. I think the machine code should be identical to what the templates produced, though I did not verify. This was a strictly mechanical conversion, less error prone than reimplementing from scratch I would think. I expect the rest of the back conversions to be similarly mechanical. Regards, Daniel
