I mean, when you need to use intensively operators, there are lots of 
(small) issues, difference between 1.8.x and 1.9.x, difference with 
JRuby with --1.9 switch... Actually, I'm using operators overloading for 
a DSL to accept new If/Else/Elsif expressions, and have to deal with 
those issues.

For example the unary +@ operator on symbols is not really working in 
1.8.x. As well as the ! operator that was finally introduced in 1.9.x. 
For the Fixnum, i didn't find any documentation (until here) that states 
that +@ operator for numeric are in fact consumed by the parser as 
literals...
