For those that lack imagination about possible use cases, here is mine: generating unique (in the scope of the request) alphabetic ids: function nextid(): string { static $id = 'zz'; return ++$id; } But no over-engineering please: no class and no decrement equivalent (the latter could be added in a separate RFC if it is really deemed useful), just a plain function that replicate the current behaviour for strings of the form /^[A-Za-z0-9]*$/, minus the bugs around the peculiar notion of “numeric string” (e.g., "9E1" equivalent to 90). —Claude
