I know of two separate and independent reasons why fucntions with OUT arguments (or IN OUT arguments; I'll just say OUT in the remainder of this message)might not be a good idea.
(1) They can be confusing, and
(2) you can't call them from SQL statements.
My reasons for (1):
They are potenially confusing, because people usially expect the function value (alone) to pass information back to the caller. I like to write code that works. I like to avoid writing code that doesn't work, even if the reason is simply because someone else didn't read the documentation carefully. Notice I didn't say "Never write a function with OUT arguments", I said think carefully before you do. I believe there are good uses for such functions. I also believe that there are good uses for duct tape, and those good uses account for maybe 1% of the actual applications. (By the way, DML in stored procedures is another thing that is done far more often than it should.)
If one of these reasons doesn't apply in your case, you should still consider the other reason.
