Others with better imagination or Unix-like system hackery skills than
myself may respond with a way, but my first inclination is 'no'.  In
particular, normally what you type at the REPL is being read from standard
in.

Perhaps if you had a way of changing the Clojure REPL function executed
when you type the command 'lein repl' read from a different Unix file
descriptor than 0 (the one for stdin), _and_ you found some way for the
terminal/console/whatever to have keystrokes you type go to that file
descriptor rather than 0, that would do it.  That second part sounds like
the trickiest bit to me.

Have you look at named pipes?  By creating one of those, and cat'ing the
file you want into that named pipe, you could start a REPL in the usual
way, type commands into it, and when you were ready, open the named pipe
and read from it.
