# This file is a part of Julia. License is MIT: http://julialang.org/license

# Deprecated functions and objects
#
# Please add new deprecations at the bottom of the file.
# A function deprecated in a release will be removed in the next one.
# Please also add a reference to the pull request which introduced the
# deprecation.
#
# For simple cases where a direct replacement is available, use @deprecate:
# the first argument is the signature of the deprecated method, the second one
# is the call which replaces it. Remove the definition of the deprecated method
# and unexport it, as @deprecate takes care of calling the replacement
# and of exporting the function.
#
# For more complex cases, move the body of the deprecated method in this file,
# and call depwarn() directly from inside it. The symbol depwarn() expects is
# the name of the function, which is used to ensure that the deprecation warning
# is only printed the first time for each call place.
