 == Why is this an issue?
 
-Other than ``++Exit Select++``, using an ``++Exit++`` statement is never a good idea.
+`Exit Function`, `Exit Property`, and `Exit Sub` are all poor, less-readable substitutes for a simple `Return`, and if used with code that should return a value (`Exit Function` and in some cases `Exit Property`) they could result in a `NullReferenceException`.
 
-
-``++Exit Do++``, ``++Exit For++``, ``++Exit Try++``, and ``++Exit While++`` will all result in unstructured control flow, i.e. spaghetti code.
