$ echo ${${v}}
ksh93: syntax error: `!' unexpected

The error message is incorrect and confusing, as there is no "!".
It should have been "bad substitution" link in mksh and bash
(note that this syntax is correct in zsh).

I've just reported the bug upstream (also reproducible with
the dev branch).
