String r1 = someFunction(r1*2, "abc");
//----------------
String r1 = someFunction((2+3+r7)*2, "abc"); // rule 1
```
2. `:%s/\(.* \)\?r\(\d\+\) = \(.*\);$\n\tr\2 = \(.*\);$/\=("\t".submatch(1)."r".submatch(2)." = ".substitute(submatch(4),"r".submatch(2),"(".submatch(3).")","")."; \/\/ rule 2")/g`

3. `:%s/int r\(\d\+\) = r\1 \([+-]\) \(.\+\);/r\1 \2= \3; \/\/ rule 3/g`
```java

//----------------
r1 -= 120*3; // rule 3
```
4. `:v/r\(\d\+\) = \(\-\?\d\+\);\n.*r\1 \?=.*/ s/r\(\d\+\) = \(\-\?\d\+\);$\n\t\(.*[ (]\)r\1\(.*\)/r\1 = \2;^M\t\3\2\4 \/\/ rule 4/g`

5. `:%s/boolean r\(\d\+\) = \(.*\);\n\tif (r\1\(.*\)$/if ((r\1 = \2\)\3 \/\/ rule 5/g`

Broken, but still cool:
- `:%s/if \(.*\) goto \(L_0x....\);$\n\(^\t.*$\n\)\+\tgoto \(L_0x....\);\n\2:$\n\(^\t.*$\n\)\+\4:/if \1 { \/\/ rule 7^M\5\t} else {^M\3\t}/g`
```java
if (r4) goto L_0x1111;
System.out.println("false");
goto L_0x2222;
L_0x1111:
System.out.println("true");
L_0x2222:
//----------------
if (r4) { // rule 7
System.out.println("true");
} else {
System.out.println("false");
}
