Lua 5.4 breaking changes revision #88
Description
I've noticed that 5.4 is breaking a lot of compatibility with 5.1 and 5.2 that 5.3 preserved. Because of that, I'll need to decide whether Turnip goes all in on the new version, or keeps to support the older ones.
Here's a handy list stolen from the Ravi language readme:
| Feature. | Ravi | Turnip |
|---|---|---|
| Generational GC | Yes | Maybe |
| New random number generator | Yes | Maybe |
| Multiple user values can be associated with userdata | under consideration. | Probably |
const variables |
not planned | #74 |
close variables |
'defer', no plans to support | Maybe |
| Interpreter performance improvements | No | No (it relies to C impls) |
| Table implementation changes | under consideration | No idea |
| String to number coercion is now part of string library metamethods | Yes | Probably |
| utf8 library accepts codepoints up to 2^31 | Yes | Definitely |
| Removal of compatibility layers for 5.1, and 5.2 | No, Ravi supports 5.1&5.2 | Maybe |
