How to apply a "doesn't contain" modifier and how to apply it to a 2-level deep multidim array

[mangrovestudios]

Hi there, this is a two-part question regarding display in antlers. I'm using the Simple Commerce add-on. I have a product with variants like so:

product_variants:
  variants:
    -
      name: Size
      values:
        - S
        - M
  options:
    -
      key: S
      variant: S
      original_price: 4990
    -
      key: M
      variant: M
      original_price: 0

I would like to condition content on the front-end based upon the existence of 0 in the product's variants' options original_price fields. For that, I would imagine something like this:

if product_variants:options:original_price | contains:0

How could I achieve that? Ie. apply the contains modifier to an array of plucked original_prices.

Additionally, is there a way to effect a doesn't contain modifier? Something akin to !contains?
