 Below are some examples of common use cases demonstrating the capabilities of vim-argwrap. Note that the extension

+functions identically regardless if it is being applied to a function call, list or dictionary definition.
 
 Let's begin with a simple function invocation. When there are many arguments being passed to the function, we often wish
 to wrap them to improve code readability. If you position your cursor anywhere between the parenthesis and execute the
 `argwrap#toggle()` command, the argument list will be wrapped to one per line.
