# frozen-string-literal: true
#
# The symbol_aref extension 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
#
# If you are using Ruby 2+, and you would like to use refinements, there
# is a refinement version of this in the symbol_aref_refinement extension.
#
# Related module: Sequel::SymbolAref
