------------------------------------------------------------
Currently, this is by design rather than a bug. Groovy treats the semicolon as
a statement separator not statement terminator like in Java.
As another example, inside the collect below, there is an expression returning
4 then an expression returning the result +3 (which is just 3) and for Groovy
there is an implicit return of the last expression:
{code}
assert [3] == [1].collect {
4
+ 3
}
{code}
Having said that, we do look ahead for closure left curly braces inside
builders for instance. In theory we could enhance the grammar to handle
additional cases like the equals but obviously not for all symbols (e.g.
changing the '+' as per the above example would break existing code).
