Unless there is some commitment to API stability, this is actively harmful.  
If you are writing functions to be consumed generally, and not just within 
your program/module/whatever, then you have to take on some additional 
responsiblities.  If you don't, then whoever tries to take advantage of your 
code is in for a world of hurt.

As you say, when it's design for it, this is great, but not for general 
application code.
