I am doing REST interface with vibed. And thinking about 
handling errors, if users forgot to pass all expected args in

For example:
foo(int x, int y) // get request
{

}

/api/foo?x=111

And if user is forgot to pass `y` we will get error in the 
browser. What is the right way to handle curch cases?

Wrap is with try-catch looks wrong.

It's seems I found how to do it
