**Explanation**: We run the original `Json.parse(File.getContent())` snippet in a macro function so it will execute when Haxe compiles our calls to `JsonMacro.load()`. Instead of returning the JSON object, in macros we need to return _syntax_. So we must convert our JSON object into Haxe syntax – just as if we'd typed our JSON out manually as Haxe objects. Fortunately there's a built-in operator for converting values into Haxe syntax, it's the ['macro-reification-value-operator': `$v{ some-basic-value }`](https://haxe.org/manual/macro-reification-expression.html). We could also use [`Context.makeExpr(value, position)`](https://api.haxe.org/haxe/macro/Context.html#makeExpr) to do the same job. We wrap the JSON reading in a `try-catch` so we can tidy-up error reporting a little.
