Class: SyntaxTree::FCall
Overview
FCall represents the piece of a method call that comes before any arguments (i.e., just the name of the method). It is used in places where the parser is sure that it is a method call and not potentially a local variable.
method(argument)
In the above example, it’s referring to the method
segment.
