`static name :: ...` was redundant — instance methods always declare
`self: *Self` as their first param by convention. The parser now derives
`is_static` from the first param's TYPE: if it's `*Self` the method is
an instance method; anything else (including no params at all) is a
class method. Removes a token from the surface, keeps the dispatch
behavior identical.
The receiver param's NAME doesn't matter — only its type. Calling the
first param `this`, `me`, `receiver`, etc. is fine as long as the type
is `*Self`. This mirrors how the rest of sx handles receiver dispatch.
Migration of every site that used the keyword:
- `library/modules/platform/android.sx` — `SurfaceView.new(ctx)`.
- `examples/ffi-jni-class-03-static.sx` — `Math.abs(n)`.
- `examples/ffi-jni-main-03-ctor.sx` — `SurfaceView.new(ctx)` in the
`#jni_main` body.
- `examples/ffi-objc-dsl-05-static.sx` — NSObject's `.class()` /
`.description()`.
164/164 example tests; chess clean on macOS / iOS sim / Android via

Flip the surface semantics for type-introducer directives: bare
`Foo :: #jni_class("path") { ... }` now means "DEFINE a new Java class
at that path" (sx-side provides the implementations). The `#foreign`
prefix modifier flips it back to "REFERENCE an existing class on the
foreign runtime." Matches how `#foreign` already reads in sx for C
function declarations (`printf :: ... #foreign;`).
Foo :: #foreign #jni_class("path/to/Foo") { ... } // reference
Foo :: #jni_class("path/to/Foo") { ... } // define
Foo :: #jni_main #jni_class("path/to/Foo") { ... } // define + main Activity
Compiler-side changes:
- New `hash_jni_main` lexer token (the launchable-Activity marker).
Existing `hash_foreign` is reused; no new modifier token there.
- `ForeignClassDecl` gains `is_foreign: bool` + `is_main: bool`.
`ForeignMethodDecl` gains `body: ?*Node` so defined-class methods
can carry sx-side implementations (foreign-class methods stay
`;`-terminated).
- Parser learns `tryParseForeignClassPrefix` — peek-and-consume the
modifier tokens, then dispatch to the unchanged
`parseForeignClassDecl` with the flags threaded through.
- Sema rejects two illegal combinations: `#foreign + #jni_main`
(can't be both an external reference and the app's main entry),
and bodied methods on `#foreign` decls (foreign methods are
runtime-provided).
- Lower's foreign-class dispatch errors on non-foreign decls with
a pointer to the runtime-synthesis follow-up; defined-class
codegen (Java class emission, RegisterNatives wiring, manifest
entry generation) lands in a separate session.
Migration:
- `library/modules/platform/android_jni.sx`: all four foreign class
decls (`Activity`, `Window`, `View`, `WindowInsets`) gain `#foreign`.
- `examples/ffi-jni-class-{01..08}*.sx`: every test's `#jni_class` /
`#jni_interface` / `#objc_class` / `#objc_protocol` / `#swift_class`
/ `#swift_struct` / `#swift_protocol` usage gains `#foreign`. All
9 files mechanical perl rename; snapshots unchanged.
Verified locally:
- `zig build test` clean.
- `bash tests/run_examples.sh` 129/129.
- `bash tests/cross_compile.sh` 3/3.
- Chess APK rebuilds, reinstalls, launches on Pixel; safe-area
clearance preserved.
`Math :: #jni_class("java/lang/Math") { static abs :: (n: s32) -> s32; }`
should parse, today's 2.2 parser treats `static` as a plain
identifier and errors at the following `abs`. The make-green
follow-up adds a `static` keyword recognition step in the body
loop and an `is_static` flag on `JniMethodDecl`.
