Represents a method call, in all of the various forms that can take.
foo ^^^ foo() ^^^^^ +foo ^^^^ foo + bar ^^^^^^^^^ foo.bar ^^^^^^^ foo&.bar ^^^^^^^^
The object that the method is being called on. This can be either ‘nil` or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
foo.bar ^^^ +foo ^^^ foo + bar ^^^
Represents the name of the method being called.
foo.bar # name `:foo` ^^^
Represents the arguments to the method call. These can be any [non-void expressions](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
foo(bar)
^^^
Represents the block that is being passed to the method.
foo { |a| a }

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.
