The parser defines the grammar. This is quite common in mainstream languages -- iirc, only after some years did python get a formal description of a grammar.

- layer8 2y ago> The parser defines the grammar. But how can you have assurance which grammar it defines, or that it even defines a well-defined grammar? I’m well aware that some languages don’t bother defining a proper grammar, or define it without having a mechanism to ensure their implementation matches it, but lacking that assurance is exactly the drawback of not using a parser generator.
