Maybe `missing` should be handled orthogonally to this issue, with an `allowmissing` keyword? I think errors on scalars (for example symbols) are unexpected: since numbers (the most common scalars) work,...

Good point about taking no `length` seriously. I also haven't seen a real-life case... I guess flattening a heterogeneous column is uncommon. So maybe not worth adding a `scalars` or...

> You mean you find `x = groupkey.x` much cleaner than `x = first(groupdf.x)`? :-D If you count the additional `do groupkey`, then it's actually longer! Following https://github.com/JuliaLang/julia/pull/39285, in Julia...

Searching for these codepoints on https://unicode.org/charts/ gives https://www.unicode.org/charts/PDF/U1F0A0.pdf which describes the series as >These characters are used to represent the 52-card and 56-card variants of modern playing cards, as well...

Agreed, though I still think it would be nice if `@chain` blocks were composable with other pipeline code (mainly because for me a `@chain` block is often a logical unit,...

Yes in practice I solve it with a small `alphaguess` and trying different starting values. I had the vague idea that "convergence in one iteration" might be a good heuristic...

I was also bitten by this. By the way, a similar confusion can arise with simple `chains[[...]]` indexing: ```julia julia> chains = Chains([10i+j for i in 1:2, j in 1:5],...

It would be nice to have `Tables.istable` return false for something like ```julia julia> [(a=1, b=2), (c=3, d=4)] 2-element Vector{NamedTuple{names, Tuple{Int64, Int64}} where names}: (a = 1, b = 2)...

Regarding the support for `mapping(x, y)` as shorthand for `mapping([x], [y])`, I thought it could be useful to have a list of accepted types, to see how this would fit....

Yes this was reported before in https://github.com/JuliaPlots/AlgebraOfGraphics.jl/issues/207 I think `table(...)` would fit well, but it's more likely than `with` to be a variable. On the other hand I would not...
