Consecutive statements with an identical first (leftmost) part can be combined into a "chained" statement using the chain operator codice_6. The common part of the statements is written to the left of the colon, the differing parts are written to the right of the colon and separated by commas. The colon operator is attached directly to the preceding token, without a space (the same applies to the commas in the token list on, as can be seen in the examples below).
