Add information messages to support DRY principle (Don't repeat yourself)

According to the DRY principle (Don't repeat yourself *) programmers should avoid or reduce redundancy in an entire program or business application. We think that the compiler and/or optimizer could detect such redundancy in a single source and would like to have compiler information messages issued for that.

    While this would be very good, this RFE is too broad and encompassing for us to contemplate doing it. It would be better if a one or more smaller RFE's were opened that targeted smaller. more incremental items. For example, this isn't quite an example of DRY, but the compiler could flag that looked like

    if a = 'abc' | a = 'def' | a = 'ghi' | ... then

    and suggest it be changed to

    if inlist( a, 'abc', 'def', 'ghi' \, ... ) then

    or to open an RFE that would request the compiler optimize this undercovers by turning it into INLIST (or whatever it deemed fit) as it does for SELECT statements (in fact this would be a very good RFE to open as there are some good things the compiler could do to either kind of this IF statement
