Implicit local array variable looses it's magic alternate personality as an
object. Commented out is equivalent working code.

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.2.8)
Gecko/20100723 SUSE/3.6.8-0.1.1 Firefox/3.6.8

If you use the implicit local variable as an object to e.g. get the upper bound
or sth else the compiler doesn't seem to know if the function should be called
recursively. Btw.: what should "Huh?" tell me?

Reproducible: Always

Steps to Reproduce:
1. Try to compile TestCase3.vb
Actual Results:  
A "Huh?" exception complaining about the functions parameters I didn't specify.
