Currently, this does not work:
```julia
julia> is = [1,2]
2-element Vector{Int64}:
1
2
julia> "$.is" # currently a syntax error
2-element Vector{String}:
"1"
"2"
```
But it should, right? For completeness sake?
Allowing `$.` as a broadcasting operation should be non-breaking since `"$."` is invalid.
It would make type-inference slightly more involved, since `"..."` can now also be an array of strings.

I don’t think that should work, no. You are interpolating into a single string, it should return only a single string.

`$` interpolation is just syntactic sugar for calling `string`, e.g. `"foo $x"` is equivalent to `string("foo ", x)`, so you can broadcast `string.(...)` if you want.
