Haskell's solution to this problem is also excellent and needs to be better known and copied into newer languages. The language has curly braces around the bodies of 'let', 'case', 'where', and 'do' constructs, and also the bodies of modules, and semicolons between the constituents of those constructs -- but when the compiler demands a '{' and doesn't see one, it uses indentation to insert them in the obvious places. If your indentation is incorrect, you're likely to get an implicit ';' or '}' put in the wrong place, and you go fix it.

The scheme works so well that people will often go months into their Haskell education before they encounter code with explicit braces and semicolons.
