+x is a unary expression.

Does not compile, the binary expression is not complete.

There is some special handling for 1. 
(ending with a dot) due to Delphi/TP compatibility, they accept it.

kr4: Same as kr1 in FPC, but Delphi does not accept it.

Same as kr1, but not accepted by Delphi.

kr6 does not compile, although I don't see why if kr5 is accepted..

Delph does not accept it.

kr8 Does not compile, probably same reason as kr6. Delphi does not accept it.
