This is a losing proposition. Because just like in Python, it may also generate endless debates on "ok, but what exactly is the idiomatic way for this particular thing here"? Is it A, or B, or maybe C? Since many are always possible, each optimizing for slightly different things, like simplicity, or maintainability, or performance, or readability, or coverage, etc. Groups may form furiously asserting that the idiomatic way must be C, others defending B, or A, and for what. Why does it matter? A young language free from cruft, after a long history of various decisions that led it on certain paths, can boldly claim such nonsense, but makes one wonder how it may look in 30 or 40 years, when other languages/ecosystems will point at its mistakes. Arguably Perl had it right all along, it's just a simple fact of life, expressed in such a generic manner that there is no need to fight it, since it's obviously true. Python's retort at the time was just clever marketing (aka lies), that worked (fooled a lot of people), it targeted Perl specifically just because that was the main competition back then.
Are you a Perl dev?
Because something bad might happen in 30 years is not the reason to make sure it happens in three...
