Here is an example of a twisted "colon and comma" logic from SAP ABAP 4 programming language:
UPDATE contacts SET: CITY = 'WARSZAWA', PHONE = '+48 22 1234567' WHERE ID = '000899888'.
This statement will update CITY for all rows and PHONE for the row with ID = '000899888'. The reasoning behind this is that by putting a colon we actually start defining statement chains: statements separated by commas. The whole thing ends with a full stop, which marks the end of every statement in ABAP 4.
This concept will be very weird to all SQL programmers.
