Error using @set with variable names that contain subscripts (sometimes errors)

[BradenDKelly]

When I apply the following and the "ij" are subscripts, the below error occurs after being called a few times for k = 1:3 rᵢⱼ = @set rᵢⱼ[k] = vector1D(rᵢ[k], rⱼ[k], box) end

however, it works fine if I use rij (no subscripts) instead of "rᵢⱼ"(ij are subscripts).

rᵢⱼ =rij= SVector{3}(0.0,0.0,0.0) initially. ri and rj are also the same size SVectors. The error happens after several successful calls, and, does not happen in a different function where this is also applied in the same manner.

Just thought I would let you know. The error message is below

Thanks for reporting. Can you provide a self contained runnable example that produces the error? Your snippet misses context and is not runnable. By the way, you can highlight code by wrapping it in backticks like this:

```julia
for k = 1:3
rᵢⱼ = @set rᵢⱼ[k] = vector1D(rᵢ[k], rⱼ[k], box)
end
```

(@jw3126 I guessed you might want to write something like above so I edited it in-place. Feel free to revert it back.)

Sorry about the very late reply. April was a busy month :S

I found the mistake, and it was mine not yours. I had accidentally used the same name twice, so upon using @set a second time, it was trying to @set a Float64 rather than a SVector{3,Float64}.

For future me, be careful when using Julias fancy fonts which allow subscripts etc...
