### The longer answer

The longer answer is a little more involved: Gatsby borrows a technique from
[Relay](https://facebook.github.io/relay/) that converts your source code into an [abstract syntax tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree) during the build step. [`file-parser.js`](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/internal-plugins/query-runner/file-parser.js) and [`query-compiler.js`](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/internal-plugins/query-runner/query-compiler.js) pick out your `graphql`-tagged templates and effectively remove them from the original source code.

This means that the `graphql` tag isn’t executed the way that you might expect. For example, you cannot use [expression interpolation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#Expression_interpolation) with Gatsby's `graphql` tag.
