I would like to change the name of a variable within a for loop, using the loop index in the name of the variable.
I’ve tried the following syntax:
```julia
A= [1,2,3]
nargs = length(A)
for i = 1:nargs
global x{i}
x{i}=A[i]
end
```
This isn’t the right syntax, and googling has not led me to the correct syntax.
I’ve also tried
```julia
A= [1,2,3]
nargs = length(A)
for i = 1:nargs
global x$i
x$i=A[i]
end
```
My hope is to create three variables, x1, x2, and x3 each containing the appropriate element of A. I will not know the size of A beforehand, which is why I thought to do it this way.

This works:
```julia
for i = 1:nargs
@eval $(Symbol(:x, i)) = A[$i]
end
```
But you will pretty much always be better off using a vector or tuple instead, so I really wouldn’t recommend using this in non-toy code. You also don’t need `global` here, since `eval` always works in global scope.

Thank you!
