Pattern to match with the start of a partition

[dakotahNorth]

There is no way with match_recognize in Esper to stay match with the start of the partition.

Would be fantastic to have the ability, like the ^ in snowflake, to match with the start of the partition.

The following pattern matches a stock with a price greater than 75.00 at the beginning of the partition:

pattern (^ gt75)
define
    gt75 as price > 75.00

In PATTERN (^ GT75), the first row (not the second row) must have a price greater than 75.00.
