# shame on you.
const ARG_NOT_SET = '_*_argument_*_is_*_not_set_*_'
# This hash holds the objects that are being watched, the signals that are being
# watched, and an array of arrays that contains arguments that were passed
# each time the signal was emitted.
#
# For example:
# _watched_signals => {
# ref1 => {
# 'signal1' => [[], [], []],
# 'signal2' => [[p1, p2]],
# 'signal3' => [[p1]]
# },
# ref2 => {
# 'some_signal' => [],
# 'other_signal' => [[p1, p2, p3], [p1, p2, p3], [p1, p2, p3]]
# }
# }
#
# In this sample:
# - signal1 on the ref1 object was emitted 3 times and each time, zero
# parameters were passed.
# - signal3 on ref1 was emitted once and passed a single parameter
# - some_signal on ref2 was never emitted.
# - other_signal on ref2 was emitted 3 times, each time with 3 parameters.

# parameters when dynamically calling a method via call (per the Godot
# documentation, i.e. some_object.call('some_method', 1, 2, 3...)).
#
# Based on the documentation of emit_signal, it appears you can only pass up
# to 4 parameters when firing a signal. I haven't verified this, but this should
# future proof this some if the value ever grows.
