to_runnable treats assignment to a variable as initialization/declaration unless is_ref is true. if the variable doesn't exist yet, it will be created. for custom parser implementations, this means that making all variable assignments ones where is_ref is true will work just fine, but explicit declarations can be done by setting it to false if desired. always leaving it at false will repeatedly shadow the variable, so this isn't recommended although it does work.

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.

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!

added var_name var_type = statement syntax, which forces the statements return type to fit in var_type. This is useful if your initial value doesn't cover all types (like [ ...], which is a list with an inner type that cannot exist because there are 0 valid types, making the list completely useless. but arr [int/string ...] = [] expands that inner type to int/string, making the list usable)

added iterators: any function that takes no arguments can be used in a for loop. Each iteration, it will be called once. If its value matches, the for loop will execute its block with that value. If the value doesn't match, the for loop will stop. This also required adding function types: fn((input11 input12 output1) (input21 input22 output2)). The type maps inputs to outputs, because the add function isn't add(int/float int/float) -> int/float, but rather add((int int int) (int float float) (float int float) (float float float)) (notice that add(int int) can't return float and any other add can't return ints).

implemented working float literals and removed the 5,2 workaround: 5.2 is now a float! (see 10.5.debug()).
...
this was an issue for so long because it requires an exception to the usual dot syntax, and exceptions can be dangerous. So if there is an issue, you can resort to { 10.5 }.something() or { 10 }.5 (although this doesn't make sense) to convince the parser to do what you want.
