[rules-users] Finding a sequence within the data

[Greg Barton]

Never underestimate the value of data structures. 
Give LabResult a pointer to the next (or previous)
LabResult.  Then the rule becomes more comprehensible:

$l1 : LabResult( value < 1, eval( inLastMonth(date) )
$l2 : LabResult( value < 1, eval( inLastMonth(date),
next == $l1 )
$l3 : LabResult( value < 1, eval( inLastMonth(date),
next == $l2 )

It's also more easily extensible to longer sequences.
