Basic test cases for nil
Trivial class to hold typed value
Basic support for using value type to change behaviour for %s(if ..) and %s(while ..)
Prevent true/false/nil from being handled as method calls
Add #to_s to Class
Add 'real' true, false, nil
Removed hacky true/false, and updated #puts to work with the typing change
Ensure 'special' names like true, false, nil are not treated as variables
String is obviously not nil
IO objects are by default not files
Test case for && / || regression related to adding typing to if
Fixed String#== for typed if
Support for typed and/or
Improved debug output
