so…. im under the (maybe mistaken) impression that if i were to have a running racket program.

i should be able to “enter” sub modules of that program and tinker with them while its running.

is that true ?

i.e. main.rkt starts a gui and leaves me on the REPL, i could then enter a submodule “data.rkt” and run functions that are defined within that module but not provided out ?

and (assuming the answer is that its possible) is that done with https://docs.racket-lang.org/reference/interactive.html?q=Enter%20Module#%28mod-path._racket%2Fenter%29 ?
