I hope this doesn't come off as just being picky but my perspective is
that of someone who is about to switch from using ksh93 as main
scripting shell to bash.

So I'm interested in what I might run into.  So far it looks like it
would be ALMOST as easy as symlinking ksh to bash in /bin.

The two big things I see that will cause that not to work are lots of
calls to `print' and that bash does not understand the easy way you
can create an array in ksh:
  `set -A array somecmd'  
creating an array of the output of somecmd.

So the print calls and array creation would cause failure in nearly
all my scripts.

Someone on comp.unix.shell pointed out I could create a 
     `print() { echo -e "$@" }'
function in bash and add that to my old ksh scripts.  So that would
cover the print calls in most cases but still pondering the array
part.

I don't have so many with array calls but enough that it would be some
work to fix.

But back to your comments. "The bugs. [...]"

Can you cite some actual examples of what you are talking about, with
enough detail so I can see what you mean?  Maybe include one or two of
the workarounds you are tired of dealing with?
