module ActiveScaffold
# Exposes a +configure+ method that accepts a block and runs all contents of the block in two contexts,
# as opposed to the normal one. First, everything gets evaluated as part of the object including Configurable.
# Then, as a failover, missing methods and variables are evaluated in the original binding of the block.
#
# Note that this only works with "barewords". Constants, instance variables, and class variables are not currently supported in both contexts.
#
# May add the given functionality at both the class and instance level. For the former, use +extend+, and for the latter, use +include+.
