I made a small post describing [how to do a documentation PR directly by the github interface (no fork required) here](https://discourse.julialang.org/t/use-and-documentation-of-and/39882/7).

Because some questions arose, [I explained a little better in this post](https://discourse.julialang.org/t/test-for-existence-of-a-variable/42845/28) and, continuing in that thread, [I made a screenshot too](https://discourse.julialang.org/t/test-for-existence-of-a-variable/42845/33).

Again, I would say bug. But opening an issue would be best.

I don’t know about documented, your question, but `echo` will not be portable to Windows. I’m not on Windows, do newlines as part of a command translate to there?

It works in backticks:

```julia
julia> `ls $1+2`
`ls 1+2`

```

I’m not sure why `"ls $1+2"` is different.

</div>

So, I think `"ls $1+2"` is probably a programming error. I’d say the problem is with backticks. I think the interpretation should be `$` could have a symbol following or should require `()`. However, I’m not sure the part about permitting arbitrary expressions after is a great idea.

Anyway, I made another ticket for a subset of this.
