there are now 10 languages so it's too late to completely overhaul the kata. there is another kata about the more general case

super

added to JavaScript and CoffeeScript, + upgrade to chai assertions. random tests only missing in Swift

Thanks, this helped me debug and understand interning 1 step further.

st = {'a': '(', 'b': '(', 'c': ')', 'f': ')f'}
st['d'] = ''
st['d'] += ')'
st['e'] = ')'
st['e'] += 'f'
st['g'] = ')f'
print(st['a'] is st['b'])
print(st['c'] is st['d'])  # Single characters get intern-ed regardless
print(st['e'] is st['f'])  # Multiple characters assigned across lines DONOT get intern-ed
print(st['g'] is st['f'])

see fork for an even faster solution, with minor modifications

4. golf it! :-)

vibe coding is bad

Nice

error approving: "Language Version is invalid" for go and rust

can't be changed, you know

This should be part of the description instead of "and alternatively after that."

seems like not a CW or kata issue, closing

approved, thanks!

It gives description merge error - just fork your translation, copy-paste the new description and publish it again.
