/**
 * @internal
 *
 * This "parser" is actually a performance optimization.
 *
 * Most lines in a typical Markdown document probably won't match a block start. This is especially true for lines starting
 * with letters - nothing in the core CommonMark spec or our supported extensions will match those lines as blocks. Therefore,
 * if we can identify those lines and skip block start parsing, we can optimize performance by ~10%.
 *
 * Previously this optimization was hard-coded in the MarkdownParser but did not allow users to override this behavior.
 * By implementing this optimization as a block parser instead, users wanting custom blocks starting with letters
 * can instead register their block parser with a higher priority to ensure their parser is always called first.
