[ale] bash return and exit

[leam hall]

I've looked at a few google searches and am not sure I understand what I'm
seeing. In bash, I want to have a function do a test, and have a variable
in the calling program set based on the function's actions. So far it seems
as if I have to either "echo" the result or have the calling function use
$?.

Calling script:

MY_VAR=`my_function`

# This fails:
my_function() {
  do_something
  return $?
}

# This works:
my_function() {
  do_something
  if [ $? -eq 0 ]
    echo 0
  else
    echo 1
   fi
}

The first function works if the parent's calls:

MY_VAR=`my_function; echo $?`

Am I looking for something that's just not in bash?
