Essentially, I am looping over indices and I need to use those indices to create symbolic variable names.

A simplified version of what I am trying to do as shown using SymPy:

```
vars=[]
for i=1:5
for j=2:7
push!(vars,symbols("x$i$j"))
end
end
```

In actuality, the indices are all coming from a list so it is not straightforward to program using for loops.

The only method for defining symbolic variables I can find for Symbolics.jl is

```
@variables x1
```

Does anyone have suggestions for how I can incorporate the x$i symbolic variable construction in Symbolics? Thank you.
