; Assume other uppercase names constants.

; NOTE: In order to distinguish constants we highlight

|

; is not suitable for all occurrences e.g. it will highlight
|

; an uppercased method as a constant if used with no params.
|
|
; Introducing highlighting for those specific cases, is probably
|
|
; best way to resolve the issue.
