ClojureScript-REPL-Test
# Build and run then open browser to http://localhost:9000/hello.html.
# Then open browser console. It has an error message like this:
# Uncaught TypeError: Cannot read property 'Jf' of undefined hello.js:6587
# Also the REPL hangs.
# If I replace :advanced with :whitespace in project.clj then the browser
# console reports no errors. Also the REPL works fine.
# Make test directory.
