> Readability counts Almost all Python programmers should be familiar with list comprehensions - this should be easy to understand: parts = [... if isinstance(item, Interpolation) else ... for item in template] Instead the example uses an explicit loop, coupled with the quirks of the `match` statement. This is much less readable IMO: parts = [] for item in template: match item: case str() as s: parts.append(...) case Interpolation(value, _, conversion, format_spec): parts.append(...) > [Ruby] is awful to read I think for someone with a basic knowledge of Ruby, it's more understandable than the Python. It's a combination of basic Ruby features, nothing advanced. I don't particularly love Ruby's syntax either, though - I think the ideal implementation would be something like: fn stringify(item) => item.is_a(Interpolation) then item.value.convert(item.conversion).format(item.format_spec) else item.to_string() fn f(template) => template.map(stringify).join()
