Personally, I wouldn't mind this. I only use {} on single lines
(as many do).

They already look very different. Why not let them behave as
differently as they look?

I do think the "generic rescue" might impose a little extra work
(a lot?) on the interpreter.

For example, when we see "begin" we know there's a good chance
we'll be seeing a "rescue." Once this is changed: When we see "do"
we're not sure whether to expect a rescue or not. Couldn't this
impact code generation (interpreting in this case) as well as
parsing? (Disclaimer: I know little about interpreters.)
