I accidentally discovered that Groovy 2, in contrast to Java, allows you to apply the ++ and -- operators to the left and right sides of variables simultaneously.
int i = 0 ++i++ assert i == 1 and you can also chain them in a single statement provided you apply parens int i = 0 ((i++)++)++ assert i == 1 ++(++(++i)) assert i == 2 ++(++(++i++)++)++ assert i == 3 I can understand allowing the chaining syntax, considering that it's roughly equivalent to next().next().next(), but as far as I reckon, being able to use these operators in such a way has no practical purpose. I haven't tried this code with the Groovy 3 parser yet--I was wondering if it supported the ++ and -- operators similarly. -Joe
