completely changed the VData/VDataEnum system: Multiple VData can share one VDataEnum via an Arc<Mutex<VDataEnum>>. If one wants to modify the data, it copies it (Copy on Write). This copying is skipped for shared mutable data (references). This was necessary for the get_ref() function. Expect bugs! 2023-05-11 01:04:15 +02:00			`list = [1 2 3 4 5 6 7 8 9 ...]`

changed assignment parser from var = statement to statement = statement left side of assignments can now be various different things instead of just variables. any statement that returns a reference can be used to assign to the value behind that reference. variables are automatically referenced, so the '&' can be omitted. if the variable contains a reference and that reference should be used, dereference it with *varname instead of just varname. 2023-05-12 00:44:47 +02:00			`// second = &list.get_ref(2).assume1()`

changed VData system again, renamed src/script to src/lang and added src/c.mers, which is an example something that currently does not work properly due to the VData implementation (and serves as a reminder to fix the issue) 2023-05-14 00:11:36 +02:00			`should_not_be_changeable = &list.get(3).assume1()`
