Feature: Visualize matching parentheses in the REPL #1556
Description
REPLs of many other lisps implement a feature where typing a closing parenthesis causes the cursor to visually jump backward to the matching opening parenthesis. This makes longer- and especially multi-line -entries in the REPL much more ergonomic, eliminates manual paren back-counting, etc. I've made this issue to see whether the lack of this or any other such balance visualization constitutes an intentional omission, or if it's a feature that might eventually make its way into Janet. If the project is open to it, if needed, I'm open to writing the requisite code myself and requesting a merge subsequently.
