Unclear output of IF "FALSE

[jasonsikes]

The IF command outputs the result of the instruction list if the condition is TRUE.

That enables the user to, for example:

MAKE "MESSAGE IF :USERNAME = "jsmith ["Welcome!]
PRINT :MESSAGE

What is the output if the condition is FALSE?

Of course, my example IS bad programming practice and probably should result in an error. It's just that the error message is unclear; an empty list is a list.

? show if "false ["hello]
Macro returned [] instead of a list
