equal `==` is not working on `reval`

RCall `reval` cannot handle empty strings, but instead throws a quite surprising error. ``` julia> using RCall julia> reval("# mycomment") ERROR: UndefVarError: `val` not defined Stacktrace: [1] reval_p(expr::Ptr{RCall.ExprSxp}, env::Ptr{EnvSxp}) @...

I created an [issue at JuliaCall](https://github.com/Non-Contradiction/JuliaCall/issues/216) however after a first inspection, I think it is actually an RCall issue. Concretely something in the following is not raising julia errors when...

Distributed.jl bug: ConcurrencyViolationError("lock must be held")

When constructing an easy but kind of complete introductory example, I am running into `ConcurrencyViolationError("lock must be held")`, while the official nested loop example which I adapted it from explicitly...

I just tried to workaround concurrancy bugs by introducing locks, but apparently I am doing something wrong ```julia using Dagger: @spawn using Distributed # add two further julia processes which...
