Current master branch:

julia> @macroexpand @varname(x[1])
:((VarName){:x}((AbstractPPL.Accessors).opticcompose((Accessors.IndexLens)((1,)))))

this branch

julia> @macroexpand @varname(x[1])
:((VarName){:x}((Accessors.opticcompose)((Accessors.IndexLens)((1,)))))

which is the right behavior and same to that with Setfield. Also ref https://github.com/JuliaObjects/Accessors.jl/blob/01528a81fdf17c07436e1f3d99119d3f635e4c26/src/sugar.jl#L271.

This should fix the exposure of Accessors issues blocking TuringLang/DynamicPPL.jl#585.
