We had it the first way until the late 1990s. I changed it to the other way while working on large proof states connected with crypto protocols. It seemed more readable to me for such proofs.
I agree with Larry. I also prefer to write foo ==> bar because my assumptions are often very long and I want to spot the conclusion immediately.
It's not too hard: Go to Plugins/Plugin Options/Isabelle/General and enter "brackets" under Print mode.foo ==> bar ==> bazAs for this last example, we definitely need the earlier syntax [|foo; bar|] ==> baz, which has been made almost impossible to enable.
