Package didn't work, but I got it do work with a downgrade hack

[PallHaraldsson]

Should it be good with this fix?

(@v1.6) pkg> add MLStyle@v0.3.1
Updating `~/.julia/environments/v1.6/Project.toml`
  [d8e11817] ↓ MLStyle v0.4.0 ⇒ v0.3.1


julia> using MLStyle.Infras

Hi, I just added CompatHelper in 998bca5 and I think for now we could just add a few compat info in the Project.toml, but I believe @thautwarm need to do some updates regarding to the MLStyle new version.

[thautwarm]

Yes, v0.4 will break some corner use. Most mLStyle users do not use those breaking features at all, but I did use a lot..

@PallHaraldsson it works now. also, do you have interests in this transpiler? this approach is solid and can even ship most of python libraries to julia.
