REPLs aren't just for learning- they are great for exploring and interactively designing programs. You are also conflating REPLs with scripting languages - the parent post already has a bunch of examples of languages suited for complex tasks that make very good use of their REPLs.
- shadowmint 12y agoThey're really not in this case. play.rust-lang.org is a bite sized code compile \ execute environment that lets you play, explore, delect different compilers and share failed build to get help. Its fantastically useful ... but its not a REPL, and being one would in no way make it more useful. REPLs are useful where a few lines can make a meaningful program. That is not the case in rust.
- tormeh 12y agoI use the REPL to try out syntax I don't quite remember and to ascertain myself of how the libraries work, something that I have to do often. It's not an absolute necessity, but it makes coding a lot faster.
