Describe the problem

I like bitmasked enums. They consume very little RAM and working with them is super fast. I often build a bunch of checkboxes that represent an option (bitmasked value).

Describe the proposed solution

Just to be able to do bind:group using a number and bit values:

<script>  // State  let options = $state(0);   // Or directly as a prop is more desirable:  let {  options = $bindable(0),  } = $props(); </script> {#each [1, 2, 4, 8] as bit} <label> <input type="checkbox" value={bit} bind:group={options}>{bit} </label> {/each}

Svelte could detect my options variable is a number and therefore assume that all values in the bound checkboxes will be numbers that are added or removed using bitwise operators.
