In case this matters, there is a typo on https://github.com/jishnub/ApproxFunSingularities.jl/blob/f265ceb42ab637b9d57257a68f5271ab3ca119f7/src/JacobiWeight.jl#L455 where I've used i instead of a as the loop variable, which wrecks type-inference.

[timholy]

Probably already fixed on Cthulhu/TypedSyntax master.

[jishnub]

Indeed, this seems to be fixed on the master for TypedSyntax. Probably needs a release
