Example: https://greasyfork.org/en/scripts/19993-ru-adlist-js-fixes/diff?v1=893106&v2=892759
Observed:

-                            args[1] = () => {
-                                eval(str.replace(/^function\s*\(\)/, 'function pwd()').replace(/if[^
-]*clientHeight[^
-]*\)\s*{/, 'if (false) {') + ' pwd();');
-                            }
+                            args[1] = () => alterEval(
+                                str.replace(/^function\s*\(\)/, 'function pwd()')
+                                .replace(/if[^
+]*clientHeight[^
+]*\)\s*{/, 'if (false) {') + ' pwd();'
+                            )();

Expected:

-                            args[1] = () => {
-                                eval(str.replace(/^function\s*\(\)/, 'function pwd()').replace(/if[^\r\n]*clientHeight[^\r\n]*\)\s*{/, 'if (false) {') + ' pwd();');
-                            }
+                            args[1] = () => alterEval(
+                                str.replace(/^function\s*\(\)/, 'function pwd()')
+                                .replace(/if[^\r\n]*clientHeight[^\r\n]*\)\s*{/, 'if (false) {') + ' pwd();'
+                            )();
