Hello!

From the documentation https://docs.julialang.org/en/v1/base/collections/:

get!(d, i) do
     i^2
end

Should this not be

get!(d, i) do i
     i^2
end

??

The do block here creates an anonymous function that captures the input argument i. The default function to get! doesn’t accept arguments.
