VB.NET Stupidisms - IsNot and AndAlso

Let's take the IsNot operator that will let you write:
If Not lMyVar is Nothingthen ...do something... end if
as
If lMyVar IsNot Nothingthen ...do something... end if
In this particular case there hasn't been any signfiicant performance or recommendation to use either form except that the IsNot operator makes the code more readable (IMHO).  Wikipedia had a funny reference to a patent application that Microsoft had filed on the operator.  While the example code above depicts using a comparison against Nothing the comparison can be done against any reference.
A more important stupidism that I thought worth posting has to do with how Visual Basic implements short-circuiting in boolean comparisons through the use of the AndAlso operator.  This allows for bypassing of future operands in the expression if a prior one determines the outcome of the evaluation.  For example, if all of the operands in an IF/THEN are evaluating to see whether the result is true, if any of hte operands return false, there is no need to continue evaluating the rest.
For example, in the evaluation below, both the first and second operand are evaluated in order to determine the result.  This results in two operatins/comparisons being made even if the first operand returns false (e.g., lValue = 10).
If lValue > 50 and lValue < 100 Then
Using a short-circuited evaluation with the AndAlso operator avoids this as follows:
If lValue > 50 AndAlso lValue < 100 Then
A friend reminded me that Basic has been this way forever and in fact Microsoft introduced the AndAlso operator to address this shortcoming.  He also scolded me for doing too much C++ development as of late.  Wikipedia has a great reference that includes a table (included in this posting) outlining how various languages provide for short-circuited boolean evaluations.
