A prism visitor that builds Sexp objects.
This is the name of the file that we are compiling. We set it on every Sexp object that is generated, and also use it to compile __FILE__ nodes.
Class
variables will change their type based on if they are inside of a method definition or not, so we need to track that state.
Some nodes will change their representation if they are inside of a pattern, so we need to track that state.

If a class variable is written within a method definition, it has a different type than everywhere else.

def op_asgn?(node)
node.call_operator == "::" || (node.value.is_a?(CallNode) && node.value.opening_loc.nil? && !node.value.arguments.nil?)
end
Call nodes with operators following them will either be op_asgn or op_asgn2 nodes. That is determined by their call operator and their right-hand side.

end
Call nodes with operators following them can use &. as an operator, which changes their type by prefixing “safe_”.
