This reverts commit c7f68a27ec.
We still think GDScript files need UIDs to allow safe refactoring,
but we're still debating what form those should take exactly.
So far there seems to be agreement that it shouldn't be done via an
annotation as implemented here, so we're reverting this one for now,
to revisit the feature in a future PR.
Within a match statement, it is now possible to add guards in each
branch:
var a = 0
match a:
0 when false: print("does not run")
0 when true: print("but this does")
This allows more complex logic for deciding which branch to take.
Which allows editable data associated with a particular class instead of
the instance. Scripts with static variables are kept in memory
indefinitely unless the `@static_unload` annotation is used or the
`static_unload()` method is called on the GDScript.
If the custom function `_static_init()` exists it will be called when
the class is loaded, after the static variables are set.
- Allow identifiers similar to keywords if they are in ASCII range.
- Allow constants to be treated as regular identifiers.
- Allow keywords that can be used as identifiers in expressions.
