It's confusing how 'REPL' refers to two different UIs:
A CLI like IPython or Julia, where things like multiline editing and syntax highlighting need careful implementation.
An editor protocol like SLIME or CIDER where multiline editing is a total non-issue.
One underrated feature of Go and Julia: methods are defined without extra indentation. In e.g. Java they're inside the the class at the next indentation level.
Methods are so common and indentation is a finite resource. "Top level method" syntax is surprising at first though.
It's funny how markdown has won in so many tools for prose, but doc comments syntax is so varied.
Rust and Julia are largely markdown, Python is ReST plus doctest syntax, and Java even an HTML dialect!
