Error encoding sparse array

[buremba]

I'm trying to encode the following value:

[{prop: 'val'}, empty value, {prop: 'val'}]

However; rison throws the following exception:
rison can't encode the undefined value

Is this the intended behavior? If that's the case, is there any workaround?

undefined should be handled gracefully.

In Javascript, empty values not equal undefined:

// empty values:
new Array(2).map(i => 1)
(2) [empty × 2]
// undefined values:
[undefined, undefined].map(i => 1)
(2) [1, 1]

It's ugly, but it is Javascript...

And I think rison should not handle empty values, let user handle it, just throw an error.

This is a huge bug for a object / JSON encoder...
