Detect GET FIRST/GET LAST without lock

[movedoa]

A rule to detect GET-FIRST/GET-LAST without an explicit lock would be nice.
Using this without a lock can lead to problems like error 2819 and other problems.

Quote from the doc:

The GET statement inherits its lock mode from
the most recent OPEN QUERY statement, unless you give a
lock-mode on the GET itself. So if you do an OPEN QUERY...
EXCLUSIVE-LOCK, and then do a subsequent GET on that
query, the GET will be EXCLUSIVE-LOCK too.

#880 is a related i guess.

I'll have a look, I thought the problem was fixed as part of #880.

The GET-FIRST and GET-LAST methods use NO-LOCK by default, so I assume you're talking about the GET statement with a modifier on a static query ? e.g.

define query qry for customer.
open query for each customer.
get first qry. // Missing lock as it's not specified in the open query statement
get next qry. // Ditto
