This will not export the functions to separate invocations of ksh.  Only
shells `spawned' by ksh to execute scripts will inherit these function
definitions.  There is no way to export functions to separate invocations
of the shell; you must do it via the $ENV file.

There aren't any.

The Korn Shell and Bash will do alias substitution first.  It's really the
last stage of token recognition rather than part of command execution.  For
bash, the order of lookup is function, builtin, file system (Posix is the
same way).  For ksh, it's builtin, function, file system.
