Is it possible to emit a warning when string literals are concatenated ? May be only when a specific option is set. The reason is that I got bitten by literal string concatenation in the following case: I have a given datamodel which contains enums in several records. Then there is code which based on the value of the enum field does certain processing. The code structure is typically like: if foo_bar in ('enum0', 'enum1', ...) then
If you forget to type the , then you get a different value to which foo_bar is never equal and you initially do not understand what is going on. A warning when the script is processed about literal concatenation would trigger some extra inspection.
This would be covered by part of MDEV-4419 that is waiting for someone to implement
