# We need to override autoload, because MRI has special behaviors associated with it
# that we can't reuse, hence we need to do workarounds.
#
# Basically, when trying to use a constant set to be autoloaded in an optionnal way, like:
# * module A; ...; end
# * A ||= 1
# When autoloading the file, the above won't work and will raise a "uninitialized constant A"
# because ruby doesn't understand that custom require is currently requiring the correct file.
#
# Our solution is to track autoloads ourself, and when requiring a path that has autoloads,
# we remove the autoloads from the constants first.
