I'm trying to set up a keybinding in my editor to enter the namespace of my 
current file in a REPL, similar to how Dr Racket's Run button works.

I can do a racket -e '(println "Hello!") -i and it loads the REPL after 
printing Hello. A racket -e '(define a "a") -i also works, in that I'm able 
to access a in the REPL. However, I can't do racket -e '(enter! 
"hello.rkt")' -i. The REPL starts, but I can't access anything defined in 
the file.

After asking in the IRC channel, I was asked to try

racket -e '(let ([racketrc-path (expand-user-path "~/.racketrc")]) (and 
(file-exists? racketrc-path) (load racketrc-path)) (void)) (enter! 
"current-file.rkt") (read-eval-print-loop)

which didn't work either. Neither did

racket -e '(enter! "file.rkt") (read-eval-print-loop)'

I can do a racket -if file.rkt if I get rid of the #lang racket line, but I 
hear using -f isn't good practice, and besides, I want to write valid 
Racket files; removing the #lang line breaks normal Racket operation; I 
can't just do a racket file.rkt.

I'd really appreciate any help in figuring out why this is happening and a 
simple fix.
