maybe a pseudo-variable fits better for this purpose.

Return codes for module functions group in three classes:
 >0 - true
==0 - exit
<0 - false

They are not very indicated to be used for returning values in the 
script, although, of course, you need different true/false values to 
distinguish among various internal behaviors of the function.
