### Current version (Cataract Creek)
-- track lvals when propagatign types, and ensure we have one when needed.
-- allow passing objects to functions by reference is requested
-- Assign/Decl to accept lvalue for assigning to reference
-- add [] as size-of-array
-- replace [foo::] declaration of array with [] - fix all main() calls
-- ensure all param passing and value return is handled correctly
-- remove all UNTESTED
+- use AddressOf instead of AssignRef
- revise all commentary
- blog post
- release
. array slices - references to arrays "foo: []bar"
- array access to read bytes from strings. How to get length? "?string[4]" ??
array[] gets length??
+- remove all tests on type->functions
+- use a type->function for performing function call
- revise all commentary
- blog post
- release
### Subsequent version
+- Maybe allow a reference to be passed to function where the by-value is expected
- 'return' statement similar to 'use', but only valid a function context
- 'return' can take no value when function has inline/transparent return value
- simple methods. Define "func type.name...." and the name will only be visible
- 'then' can extend a case section into some other.
## Needs Design
+- review {} syntax issues - look at weird test cases
+- do I need a 'rune' type? What are the elements of a string?
+ Are they small strings? Can I convert to codepoint by treating as number?
+ How much of this is in the utf8 library? Can a string literal be a number?
- exactly where does auto enref/deref happen?
.foo modifier does auto-deref
(args) modifier does auto-deref (if that makes sense)
