message: Rename variable to lowerCamelCase and mark as const
  This is a runtime constant, rather than a compile time constant. We
  should probably use lowerCamelCase for that. The value may change for
  each invocation of the function. Also, we should mark it as const,
  rather than use a variable naming convention.
