-# The from_block extension changes Database#from so that blocks given
-# to it are treated as virtual rows applying to the FROM clause,
-# instead of virtual rows applying to the WHERE clause.  This will
-# probably be made the default in the next major version of Sequel.

-# This makes it easier to use table returning functions:
-#
-#   DB.from{table_function(1)}
-#   # SELECT * FROM table_function(1)

-# To load the extension into the database:

-#   DB.extension :from_block
