class Prism::CallNode

When a call node has the attribute_write flag set, it means that the call is using the attribute write syntax. This is either a method call to []= or a method call to a method that ends with =. Either way, the = sign is present in the source.

Prism returns the message_loc without the = sign attached, because there can be any amount of space between the message and the = sign. However, sometimes you want the location of the full message including the inner space and the = sign. This method provides that.
