What's the (fastest/cleanest/straightforward) way to convert all keys in a hash from strings to symbols in Ruby?
This would be handy when parsing YAML.
my_hash = YAML.load_file('yml')
I'd like to be able to use:
my_hash[:key]
Rather than:
my_hash['key']

Here's a better method, if you're using Rails:
params.symbolize_keys
The end.
If you're not, just rip off their code (it's also in the link):
