> A rule like this

> rule "Typo"
> dialect "mvel"
> when
>   ...
> then
>   // Notice the ":" in place of ";". There is also a \n at the end of the line
>   System.out.println( "Hello" ):  
>   // more statements here
> end
> {code}
> MVEL will validate the RHS at compile time. 
> At runtime, the printout (actually any statement ending with ":") will be
> executed, but MVEL will fail silently thereafter. The rest of the conclusion
> will not be evaluated.
