// Whenever a ambient declaration changes, its number should be increased
// This way, we avoid the situation where multiple ambient versions of svelte2tsx
// are loaded and their declarations conflict each other
// See https://github.com/sveltejs/language-tools/issues/1059 for an example bug that stems from it
// If you change anything in this file, think about whether or not it should be backported to svelte-shims.d.ts
