How to interpolate when having nested macros ?

E.g., a toy example

```julia
julia> using Distributed

julia> using BenchmarkTools

julia> @everywhere function bencheverywhere()
               for k in 1:2
                       @btime sin($k)
               end
       end
ERROR: UndefVarError: `k` not defined
Stacktrace:
 [1] top-level scope
   @ ~/.julia/juliaup/julia-1.9.4+0.x64.linux.gnu/share/julia/stdlib/v1.9/Distributed/src/macros.jl:201

```
