I don't think it is a good idea to let inspected page pass some arbitrary JS
code that would be evaluated by the debugger. It is a potential security
problem. Can we avoid constructing this condition in the injected script and do
it somewhere the inspected code doesn't have access to?

Moved to C++.

+    void removeBreakpoint(DOMString scriptId, long line, long column, DOMString source);
 
     // Only declarative scope (local, with and catch) is accepted. Returns undefined. 
     [Custom] any setFunctionVariableValue(any functionObject, int scopeIndex, DOMString variableName, any newValue);
 };
