Closed - lazy evaluation is a feature of how cscc works.
Changing this will require a massive re-architect to

Summary:  cscc incorrectly resolves some using-alias-directive

Original Submission:  When handling using-alias-directives, resolving a 
typename or namespace is supposed to  be done as though each directive were the 
only one in the immediate namespace or  compilation unit. This is illustrated 
by the attached program below:

csc reports the following error:

using.cs(2,9): error CS0246:         The type or namespace name 'A' could not 
be found (are you missing a using directive or an assembly reference?)

I have partially fixed this bug.  It is now no longer possible
to have one alias refer to another, in accordance with the 
specification.  However, the test case attached to this bug 
will still compile OK with no error because B is never used
anywhere in the code.  If you add a variable declaration to
Main like "B x", you will get an error.  This is because
aliases are evaluated in a lazy manner in cscc.  It may
take a bit longer to figure out how to evaluate aliases
non-lazily.
