note audreyt Indeed, and that bugs is closed, so 6.0.11 won't parse it as <code>= =</code>. On the other hand, <code>:==$x</code> stays legal and is parsed as <code>:= =$x</code> in the absense of an user-defined <code>:==</code> operator, which I think is correct -- let me know if it's not. :) <p> The <code>for@l {...}</code> form is indeed correctly parsed; no whitespace is needed before <code>@</code>. <p> Finally, thanks to this Golf-Driven Development, nothingmuch is now implementing <code>reverse</code> as we speak, so 6.0.11 should be happy with <code>print reverse=<></code> -- note that I shaved the trailing semicolon. Yay! 438876 438947
