You also mentioned Scala. In Scala you need to write the return type to 
the function signature when explicitly using 'return'. The only case 
where this can fail in Scala is when the return type is Unit. Would be 
strange to try to return 2+2 in that case.

Andrei also mentioned this:

in Scala both

> def fun = { 42; }
> def fun = { 42 }

return the same function.

The only cases in Scala when the expression fails is when you write a 
multiline expression and forget to surround the expression with braces or 
parentheses.
