Hello, I want to shadow instead of mutate.
The ideal solution would be to create a new environment that extends the old one, so that new definitions in the new environment shadow the old definitions instead of mutating them. But if that isn't feasible with the way namespaces work right now, is there a way to copy a namespace so that mutating the copy doesn't mutate the original? If there isn't, is there a way to functionally update a namespace to add new definitions? I need this for my debug-repl package so I avoid mangling the namespace in examples like this: > (define x 1) > x 1 ; outside the debug-repl, x is 1 > (define (f x) (debug-repl)) > (f 2) -> x 2 ; inside the debug-repl, x is 2 -> ; exit the debug-repl > x 2 ; x should be 1, but it mangled the namespace Is there a way to do this without mangling the original namespace?
