That thing where you find the YAML parser you're using will parse JSON too 🤦🏼

test.swift

	func testNotYAMLFront() throws {
		let testdoc = """
---
{"title": "hello, world"}
---
"""
		// I only use a YAML parser, so this should throw
		// XCTAssertThrowsError(try FrontMatterDocument(data: Data(testdoc.utf8))) { error in
		// 	XCTAssertEqual(error as? FrontMatterDocumentError, .FailedToParseYAML)
		// }
		
		// Erm, okay, that didn't throw, but at least I shouldn't get any data?
		let document = try FrontMatterDocument(data: Data(testdoc.utf8))
		// XCTAssertEqual(document.frontMatter.count, 0)
		
		// I got data, wtf?
		print("\(document.frontMatter)")
		// Prints ["title": FrontMatter.FrontMatterValue.stringValue("hello, world")]
		
		// Dawning realisation that Yams will apparently parse JSON?
