The syntax of $past is described in 17.7.3 and 22.9 as $past( expression1 [, number_of_ticks] [, expression2] [, clocking_event]) This is not precise as it both implies that the 3rd or 4th argument may be present without at least the commas preceding the preceding arguments, and also does not show that the actual argument may be omitted as long as at least the comma is present (at least for the 2nd and 3rd arguments). A more precise syntax (though harder to read) is $past( expression1 [, [number_of_ticks] [, [ expression2] [, clocking_event]]] ) or $past( expression1 [, [number_of_ticks] [, [ expression2] [, [clocking_event]]]] ) . The difference between the two is whether clocking_event may be omitted if the last comma is present. This is Mantis 1591.
