+# CurlyWas
+
+CurlyWas is a (still WIP) curly-braces, infix synatx for WebAssembly.
+The goal is to have as to a 1:1 mapping to the resulting wasm instructions
+as possible while still being reasonably convenient to write.
+
+For this reason alone (and in no way because I'm a little lazy) does this
+compiler not implement any optimizations except for constant folding.
+
+## Example
+
+```rust
+import "env.memory" memory(4);
+import "math.sin" fn sin(f32) -> f32;
+import "math.atan2" fn atan2(f32, f32) -> f32;
+
+export fn tic(time: i32) {
+    let i: i32;
+    loop screen {
+        let defer t = time as f32 / 2000 as f32;
+        let defer o = sin(t) * 0.8;
+        let defer q = (i % 320) as f32 - 160.1;
+        let defer w = (i / 320 - 128) as f32;
+        let defer r = sqrt(q*q + w*w);
+        let defer z = q / r;
+        let defer s = z * o + sqrt(z * z * o * o + 1 as f32 - o * o);
+        let defer q2 = (z * s - o) * 10 as f32 + t;
+        let defer w2 = w / r * s * 10 as f32 + t;
+        let defer s2 = s * 50 as f32 / r;
+        i?120 = max(
+            0 as f32, 
+            ((q2 as i32 ^ w2 as i32 & ((s2 + t) * 20 as f32) as i32) & 5) as f32 *
+                (2 as f32 - s2) * 22 as f32
+            ) as i32;
+        branch_if (i := i + 1) < 320*256: screen
+    }
+}
+```
+
+You can compile this to `technotunnel.wasm` with the command
+
+```
+curlywas technotunnel.cwa
+```
+
+Then run it on [MicroW8](https://exoticorn.github.io/microw8/v0.1pre1)
