It's not so pretty, but what are the alternatives? Making indentation meaningful has downsides (copy-pasting can go very wrong) and using up ascii characters just for this means they can't do other things (like Vector{Int} type parameters) and still often takes up a line.
You can avoid it quite a bit, e.g. f(x,y) = (z=x+y; sqrt(z)) defines a function, with two statements separated by ;.
