### Phase 1

- [X] Convert some small programs
|

- [X] Error handling
|
||||
- [X] All functions return `(type, error)`
|
||||
- [X] Convert `throw` to err return
|
||||
- [X] Non-leaf function calls need to check + bubble errors
|
||||
[X] Array handling
|

- [X] Array handling
|

- [X] Infer whether to use slice/map for PHP array
|

[-] Namespaces
|

- [-] Namespaces
|

- [X] Basic support for `namespace` -> package name transformation
|

- [ ] Resolve namespace names in calls
|

- [ ] Resolve `use` statements
|

[X] `if`

|

|

- Implemented as inline closure

[X] `try`/`catch`/`finally`
|
||||
- [X] `die`
|
||||
- [X] `try`/`catch`/`finally`
|
||||
- [X] Implement using err checks, not panic/recover
|
||||
- Any statements within the try block should capture the finally/catch to run within any interior err-check blocks
|
||||
- [ ] `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

- [ ] Attempts to enable magic_quotes or register_globals
|

[X] Detect assignment expressions

- [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
|
||||
[X] Closures
|
||||
- [X] Closures
|

- [ ] Handle value/reference captures

- [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
