In Nu we have variables (E.g. $var-name) and these contain `Value` types. This means we can bind to variables any structured data and column path syntax (E.g. `$variable.path.to`) allows flexibility for "querying" said structures. Here we offer completions for these. For example, in a Nushell session the variable `$nu` contains environment values among other things. If we wanted to see in the screen some environment variable (say the var `SHELL`) we do: ``` > echo $nu.env.SHELL ``` with completions we can now do: `echo $nu.env.S[\TAB]` and we get suggestions that start at the column path `$nu.env` with vars starting with the letter `S` in this case `SHELL` appears in the suggestions.
