Is there a more elegant way of interpolating x_i = i, without having to work with strings? This is what I am using now: for i = 1:3 eval(Meta.parse("x$i = $i")) end I haven’t figured out metaprogramming yet :frowning:.

Interpolation of expression

There are lots of useful macros in Base.Cartesian for this sort of thing:

julia> @macroexpand @nextract 3 x d->2d
quote
    x_1 = 2
    x_2 = 4
    x_3 = 6
end
