 ## Progress
 
+### Phase 1
+
 [X] Convert some small programs
 [X] Error handling
 	- [X] All functions return `(type, error)`
 	- [X] Convert `throw` to err return
-	- [ ] Elide error return for functions that cannot throw
-		- ?? Could be a standalone Go refactoring tool
 	- [X] Non-leaf function calls need to check + bubble errors
-	- [ ] Behaviour of function calls in rvalue cases where err cannot be checked
-[ ] Comprehensive coverage of all AST node types
-	- [ ] Node
-	- [ ] Stmt
-	- [ ] Expr
-	- [X] Binary
-	- [ ] Scalar
-		- [ ] Heredocs/nowdocs
 [X] Array handling
 	- [X] Infer whether to use slice/map for PHP array
-	- [ ] Infer whether map use should be order-preserving
 [ ] Multi-file programs
 	- [ ] Include/Require
-[X] Namespaces
+[-] Namespaces
 	- [X] Basic support for `namespace` -> package name transformation
-	- [ ] Namespace resolution in calls
-	- [ ] `use`
-	- [ ] Support scoped namespace (`namespace { ... }`) and multiple namespaces in file
+	- [ ] Resolve namespace names in calls
+	- [ ] Resolve `use` statements
 [ ] Generators
 [ ] Numbered break/continue
 [ ] Goto

 	- [ ] `finally`
 		- Runs before any return statement inside the try block or catch block; also runs after the try block is complete
 		- Maybe `finally` would be more concisely implemented as defer inside an IIFE, but that is not idiomatic, maintainable Go code

-[ ] Assignment expressions 
+[ ] Abandon upon sight of `eval` / `extract` / variable-variables ...
+[X] Detect assignment expressions 
 	- Go doesn't support assignment in rvalues, only as a statement
 	- When walking below stmt level, need to first fully walk and check for any function calls + assignments that may need hoisting (and we can probably only do that correctly if there is no short-circuiting)
 	- [X] Add subtree walk + catch error for this case
-	- [ ] Add hoisting pass
 [ ] Closures
 	- [ ] Handle value/reference captures
 [X] Convert top-level calls to `init()`/`main()`
-	- *Currently always `init`*
+	- [X] Wrap in function
+	- [X] Determine init/main based on package name
 [ ] Class/object transformations
 	- [X] Convert `new X` constructor calls to `NewX`
 	- [X] Visibility
