after writing out a working parser in R, i asked chatgpt to translate the tokenizer to cpp11 and got a 3x speed increase. (of course, i reviewed the output and have the two parsers unit testing against each other)

Did I just hand-write an implementation of #cpp23 std::expected for use in #cpp11 ? Very, very yes.
Is it complete? No. But it is functional enough.
Am I pleased with it? Also very yes!
Will I use it in #ProjectSpecialK? I dunno, maybe. We'll see.

New on CRAN: vrpr (0.1.0). View at https://CRAN.R-project.org/package=vrpr
vrpr: Vehicle Routing Problem Solver Built on 'PyVRP'
A 'tidyverse'-style interface to high-performance vehicle routing problem (VRP) solving. Vendors the C++ core of the 'PyVRP' solver (<<a href="https://github.com/PyVRP/PyVRP" target="_top">https://github.com/PyVRP/PyVRP</a>>) and rewires it through 'cpp11', with no 'Python' runtime dependency. Supports the capacitated VRP, time windows, multiple depots, heterogeneous fleets, prize-collecting and multi-trip variants, driven by an iterated local search metaheuristic.
