+Anywhere that `String` would normally be accepted, keywords can be passed as well. In fact, any Type can be passed so long as the type has a method for the `string` function.

 For any Redis command `x`, the Julia function to call that command is `x`. Redis commands with spaces in them have their spaces replaced with underscores (`_`). For those already familiar with available Redis commands, this convention should make the API relatively straightforward to understand. There are two exceptions to this convention due to conflicts with Julia:
 
 * The _type_ key command is `keytype`

 ### Commands with options
 
-Some Redis commands have a more complex syntax that allows for options to be passed to the command. Redis.jl supports these options through the use of a final varargs parameter to those functions (for example, `scan`). In these cases, the options should be passed as individual strings at the end of the function.

 If users are interested, the API could be improved to provide custom functions for these complex commands.

 ### Subscription error handling
 
-When a `SubscriptionConnection` instance is created via `open_subscription`, it spawns a routine that runs in the background to process events received from the server. In the case that Redis.jl encounters an error within this loops, the default behavior is to disregard the error and continue on. If the user would like finer control over this error handling, `open_subscription` accepts an optional `Function` parameter as its final argument. If this is provided, Redis.jl will call the provided function passing it the caught `Exception` as its only parameter.
