That's true, but hacking the REPL is far more likely to break in future
releases.
Undocumented internal functions in Julia have a tendency to become
documented external functions when they prove useful outside of Base.
There is a reasonable case to be made for exporting and documenting
parse_input_line (although it might get renamed in the process). Maybe
open an issue?
(And you shouldn't redefine display; instead push something onto the
display stack as I explained above. For one thing, redefining display(x)
is not enough to work for code that explicitly calls display("text/plain",
x).)
