Honestly I find A(B(int)) or A[B[int]] to be clearer than A!B!int. I don't think A!B!int is horrible. I just don't think it is the best possible choice. Of course that is just my personal opinion. The sources for the experimental translation tool are available, so anybody can try the experiment you suggest. Even easier would be to rewrite the examples using the D notation, to see how they look. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
