# frozen-string-literal: true
#
# The symbol_aref_refinement extension adds a refinement that makes
# Symbol#[] support Symbol, #Sequel::SQL::Indentifier, and
# Sequel::SQL::QualifiedIdentifier instances, returning appropriate
# Sequel::SQL::QualifiedIdentifier instances. It's designed as a
# shortcut so that instead of:
#
# Sequel[:table][:column] # table.column
#
# you can just write:
#
# :table[:column] # table.column
#
# To load the extension:
#
# Sequel.extension :symbol_aref_refinement
#
# To enable the refinement for the current file:
#
# using Sequel::SymbolAref
#
# If you would like this extension to be enabled globally instead
# of as a refinement, use the symbol_aref extension.
#
# Related module: Sequel::SymbolAref
