[RFC] Define proper semantics for range() function

Hello internals, While working on analysing the impact of the changes proposed by amending the behaviour of the increment and decrement operators ( https://wiki.php.net/rfc/saner-inc-dec-operators) I discovered that the range() function has some rather lax behaviour that is very unintuitive. I therefore propose the "Define proper semantics for range() function" RFC to address the unintuitive behaviour that sees no usage and/or hide bugs: https://wiki.php.net/rfc/proper-range-semantics The change propose to throw TypeErrors and ValueErrors for case where I couldn't find occurrences in the wild and hide bugs, and emit some E_WARNINGs for cases that are hard to detect via static analysis.
