Description

We introduced a flag which can skip values when equal to nil. In some cases, it is useful to exclude values when they
just evaluate to false to be even more clean. For example:

set_type('T', {
    name: 'str',
    canBike: '!bool',
});
T{name: 'Alice', canBike: false}.wrap(); 

The above will return

{
   "name": "Alice"
}

As we wrap() and the wrap-prefix flag ! tells to exclude the properties which evaluate to false.
