Until Command wrote:

Loop Until is shorthand for the following:

Code:

Loop {
    ...
    if (Expression)
        break
}

Code:

Loop {
   obj := {}
   if obj
      break
}

Loop ; <-- infinate loop
   obj := {}
Until, obj ; not evaluating as true

Thanks for reporting it. The object is evaluating to an empty string (as documented "where an object is not expected"), which is false. If and While only work because of an optimization within ExpandExpression which is designed to return "1" (true) or "" (false) instead of copying the result into the deref buffer. Fixing it is a simple matter of adding a check for Until on the appropriate line. Incidentally, the current v2 alpha works as expected, since I had already made a similar change when revising nearby code.
