We have a few behavior deviations from Lua 5.x that come from either a different implementation, or our desire to clean up small inconsistencies in the language/libraries:
* Tail calls are not supported to simplify implementation, make debugging/stack traces more predictable and allow deep validation of caller identity for security
* Order of table assignment in table literals follows program order in mixed tables (Lua 5.x assigns array elements first in some cases)
* Equality comparisons call `__eq` metamethod even when objects are rawequal (which matches other metamethods like `<=` and facilitates NaN checking)
* Tail calls are not supported to simplify implementation, make debugging/stack traces more predictable and allow deep validation of caller identity for security
