Lua iterators like pairs() can now return specifically mutable nodes. The programmer can convert this to an immutable node if they want to store it for use after the loop, or they can test for mutability using the ismutable() method. Well, it worked. Now we have a lightning-fast ...
The recent update to pygments (version 2.19) causes the library to hang indefinitely when processing Lua code that uses spaces for indentation (rather than tabs). Since mkdocs implicitly converts indentation to spaces, anyone using it fo...

Will skip the current loop iteration. push keyword function a() for i=1, 5 do push i, "next" end return "done" end print(a()) -- 1, next, 2, next, 3, next, 4, next, 5, next, done push "hey" -- Does *not* work, because it is a valid Lua syntax for push("hey") ...
As before, we save the bonusType in lower case, since we'll be using it a lot later. Next, we open a for loop, where the index is the id of the unit type receiving the bonus, and the value is the bonus table for that unit type. Next, we duplicate the bonus tabl...
