RE: Local variable declaration enhancements -- statement scoping

[Milles, Eric (TR Technology)]

Maybe the "if" could forward declare the name(s) like this when not relying on 
Groovy truth:

if (def x; (x = ...) != null) {
}

---------

if (def x = ...) { // tests Groovy truth in this form; may be wrapped in parens 
to check something else about "x"
}
