           Summary: Boo shell creates invalid IL. This crashes mono runtime.
           Product: Mono: Runtime
           Version: unspecified
          Platform: Other
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: misc
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: emperon at gmail.com
         QAContact: mono-bugs at lists.ximian.com
          Found By: Other

To reproduce this bug:

Get boo from boo.codehaus.org (this happpens in boo 0.8.1-)

run booshell by booish.exe
type the following:
callable MyPredicate[of T] (item as T) as bool

>>>def B[of T]():
..    p as MyPredicate[of T] = {item as T|return true}
..

>>>B[of object]()

/// don't for get to put a <TAB> before p as MyPredicate.... since it's like
python

Boo creates an invalid IL this is a boo bug. But this results in mono runtime
crashing as below:
