Close and close. As of two days ago, Larry's thinking was:
BEGIN Executes at the beginning of compilation
CHECK Executes at the end of compilation
INIT Executes at the beginning of run
END Executes at the end of run
PRE Executes at block entry.
Inherited if block is a method. No side-effects
allowed.
POST Executes at block exit.
Inherited if block is a method. No side-effects
allowed.
NEXT Executes on (explicit or implicit) call to next()
within current block
CATCH Executes on exception within current block
LAST Executes on any form of block exit.
Not inherited (c.f. POST), even if block is a method.
Side-effects allowed.
KEEP Specialized form of CATCH.
Executes on "control" exception in the current block
UNDO Specialized form of CATCH.
Executes on non-"control" exception in the current
block
