OK, but I'd like to know what is going to be safe. There's no way to 
future-proof the language. I'm quite prepared to replace -> with 
something else, and if I do then ->> will need to be adjusted 
accordingly, I think.

My suggestion would be ~> and ~>>. I know David Wheeler didn't like that 
on the ground that some fonts elevate ~ rather than aligning it in the 
middle as most monospaced fonts do, but I'm tempted just to say "then 
use a different font." Other possibilities that come to mind are +> and 
+>>, although I think they're less attractive. But I'll be guided by the 
consensus, assuming there is one ;-)
