However, in many occasions, being able to let the '.' and '[...]' operators behave 'safely' without reverting to the 'lenient' mode would be very convenient. Moreover, it seems 3.1 already allow 'safe' / silent navigation when calling methods / functions; fixing this behaviour will break existing scripts. Explicitly introducing this 'safe' behaviour would mitigate the (3.2) migration cost greatly. HOW: Builder option to set the flag, inject checking the flag when node.isSafeLhs(...) is used. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
