class SyntaxTree::ARefField

ARefField represents assigning values into collections at specific indices. Put another way, it’s any time you’re calling the method []=. The ARefField node itself is just the left side of the assignment, and they’re always wrapped in assign nodes.

collection[index] = value

Attributes

collection[R]

Node: the value being indexed

comments[R]

Array[ Comment | EmbDoc ]: the comments attached to this node

index[R]

nil | Args: the value being passed within the brackets
