@ -258,6 +258,14 @@ $ uglifyjs example.js -c -m --mangle-props regex=/_$/
var x={o:0,_:1,calc:function(){return this._+this.o}};x.l=2,x.o=3,console.log(x.calc());
```
Combining mangle properties options:
```bash
$ uglifyjs example.js -c -m --mangle-props regex=/_$/,reserved=[bar_]
```
```javascript
var x={o:0,_:1,calc:function(){return this._+this.o}};x.bar_=2,x.o=3,console.log(x.calc());
```
In order for this to be of any use, we avoid mangling standard JS names by
default (`--mangle-props builtins` to override).
