At the risk of preaching to the choir, unquoted $* and $@ are dangerous.
They don't even have consistent semantics across different shells!
See <https://lists.gnu.org/archive/html/bug-bash/2017-06/msg00283.html>.

Only use quoted "$@" and "$*".  Ever.  Always.  Obviously the same
applies to the array versions, "address@hidden" and "${a[*]}".
