# This is a simpler version of allnoconfig.py, corresponding to how the C
# implementation does it. Setting a user value that's not in the assignable
# range of the symbol (between get_lower_bound() and get_upper_bound(), or,
# equivalently, not in get_assignable_values()) is OK; the value will simply
# get truncated downwards or upwards as determined by the visibility and
# selects.

# Note: This version will be very slow since Kconfiglib invalidates all
# dependent symbols for each set_value() call. This does not happen for
# load_config(), which instead invalidates all symbols once after the
# configuration has been loaded. This is OK for load_config() since nearly all
# symbols will tend to be affected anyway.
