Review comment:
Are you sure only change this point is enough？
Do we need to change this point:
FunctionCallExpr::analyzeImpl
```
Type[] args = fn.getArgs();
if (args.length > 0) {
// Implicitly cast all the children to match the function if
necessary
for (int i = 0; i < argTypes.length; ++i) {
// For varargs, we must compare with the last type in
callArgs.argTypes.
int ix = Math.min(args.length - 1, i);
if (!argTypes[i].matchesType(args[ix]) && !(
argTypes[i].isDateType() && args[ix].isDateType())) {
uncheckedCastChild(args[ix], i);
//if (argTypes[i] != args[ix]) castChild(args[ix], i);
}
}
}
```
