I love visually distinct/suggestive operators so long as they're easy to type on a standard layout. So for that reason alone I agree that a ! b is better than a <- b

With many punctuation infix operators (see Scala for an extreme case) people who don't use the language won't understand the code, and you'll have to use an appropriate search engine or emacs mode to look up docs, but it's worth it for what you get in exchange.

It would be nice for the community to standardize on unicode glyphs for enhanced visual representation of ascii-art operators like |> <- etc. (so that online syntax highlighters / code review / diff interfaces show the same as your editor). Pretty glyphs instead of mere ASCII could really help readers (the source code should still be ASCII).
