| Parent: | Object | 
The blank extension adds the blank? method to all objects (e.g. Object#blank?).
Returns a copy of the object wrapped in a Sequel::SQL::BooleanExpression, allowing easy use of Sequel‘s DSL:
false.sql_expr & :a # FALSE AND a
    # File lib/sequel/extensions/sql_expr.rb, line 52
52:   def sql_expr
53:     Sequel::SQL::BooleanExpression.new(:NOOP, self)
54:   end
