This trick -- which was always fragile because printenv is not a robust
way to do this -- will not work any more.  One of the reasons we
implemented the new exported function name encoding scheme was to avoid
name collisions with exported variables.

You can use `export -f' to generate a function definition and declaration
that you can save in a file for later use.
