also says this syntax is compatible with python which is not really true. if you have this in python: { key: "value", dr_nic: "The Comedian", ttl: 42 } python will expect there to be a variable called 'key', one called 'dr_nic', and one called 'ttl'. If you intend to do d['ttl'] you'll need to create a hash using a literal string

I am not a Ruby programmer. What's the syntax for using a variable as the key, which is actually synonymous with the Python code?
Cool. Now why doesn't PHP join the crowd and do this with arrays already?

You don't necessarily have to create a hash using a literal string. You can also do this: dict( key="value", dr_nic="The Comedian", ttl=42 ) ...but that is a bit different syntax.
Earlier quoted context omitted.

It will also make your code drastically slower.

>> a = :foobar
=> :foobar
>> {a => 1}
=> {:foobar=>1}
