@ -1251,6 +1251,90 @@ In test file `test/bf.nas`, it takes too much time to test the file because this
Upvalue now is generated when creating first new function in the local scope, using `vm_vec`.
And after that when creating new functions, they share the same upvalue, and the upvalue will synchronize with the local scope each time creating a new function.
2022/3/27 update:
In this month's updates we change upvalue from `vm_vec` to `vm_upval`,
a special gc-managed object,
which has almost the same structure of that upvalue object in another programming language __`Lua`__.
Today we change the output format of bytecode.
New output format looks like `objdump`:
