I'm the one who posted the example here, and I can confirm that in that case at least, davido's guess below (update: and LanX's above) is quite right: it's a personal formatting convention associated with the REPL I wrote for myself, which collapses all blank lines to nothing. I've seen double-semicolons used in code examples from BrowserUk, but in that case I think it has some actual, functional use in his personal REPL.

Give a man a fish:  <%-{-{-{-<
