Also, going off of the [benchmarks](https://github.com/Roger-luo/Comonicon.jl/tree/master/example) provided by @Roger-luo in his [Comonicon post](https://discourse.julialang.org/t/comonicon-jl-fast-simple-and-light-weight-cli-generator/43744), ArgMacros v0.2.2 (inline) is (just barely) faster than the latest releases of any of the other options demonstrated:
