What's stopped me from using this syntax in the past is that it means LTE in basically any language I can think of. One can certainly design a grammar where it's unambiguous, I have in fact, but it still doesn't look right to me.


R uses <- which is less ambiguous at the cost of no longer having an equals sign in it.


That sounds like a benefit to me, not a cost.


That also means they have to use spaces? Otherwise what is the difference between x <- 1 and x < -1?
