It would be really helpful to have a reference of available packages that help with metaprogramming. Maybe this could be similar to JuliaDiff or JuliaOpt, or at least a page on a wiki somewhere. Here’s some I’ve come across so far:

- [ChainRecursive](https://github.com/bramtayl/ChainRecursive.jl) by @bramtayl
- [Espresso](https://github.com/dfdx/Espresso.jl) by @dfdx
- [MacroTools](https://github.com/MikeInnes/MacroTools.jl) by @MikeInnes

Others to consider?

There are also [Sugar.jl](https://github.com/SimonDanisch/Sugar.jl) and somewhat related [Transpiler.jl](https://github.com/SimonDanisch/Transpiler.jl) by @sdanisch.

I remember several people on this forum looking for symbolic transformation tools, not aware of existing packages, so making an org makes sense to me.
