# typed: false
# frozen_string_literal: true

# On MRI Symbols can be of two types: static or dynamic
#
# Static symbols are the ones explicitly referenced in the source code (`:foo`), and they're fake objects.
# Meaning they don't actually exists, they're just a special type of reference like integers. They use close to
# no memory, are particularly fast to compare and are not garbage collected.
#
# Dynamic symbols are symbols built using `String#to_sym` and that don't have an existing equivalent static symbol.
