“Range-Based Text Formatting For a Future Range-Based Standard Library”
summary
think-cell implements a range-based formatter that treats values as lazily generated character ranges, adds an internal iteration model plus customization points called appender and chunk, and composes ranges with concat and as_dec formatters. Benchmarks show iterator-based ranges are ~50% slower than a hand-written tight loop, while internal-iteration ranges are ~15% slower; avoiding end-checks on reserved buffers saves ~20%. Code targets recent C++ compilers, still uses parts of Boost, and is on GitHub under a Boost license.
