1. SyntaxTree::
2. DynaSymbol

DynaSymbol represents a symbol literal that uses quotes to dynamically define its value.

:"#{variable}"

They can also be used as a special kind of dynamic hash key, as in:

{ "#{key}": value }

nil | String

the quote used to delimit the dynamic symbol

def initialize(parts:, quote:, location:)
  @parts = parts
  @quote = quote
  @location = location
  @comments = []
end

  other.is_a?(DynaSymbol) && ArrayMatch.call(parts, other.parts) &&
    quote === other.quote

  visitor.visit_dyna_symbol(self)
