The contexts in which jmd files are used (e.g. writing reproducible reports) are akin to those of IJulia. Also, it is usual to try the code chunks in the REPL during the writing of jmd files. Now that the REPL (in Julia 1.5) uses soft scope in loops, as IJulia did, it might be reasonable to extend that behavior to weaving jmd files, and provide a consistent experience in all three environments.
