In autoloaded environments which reference
::Collection
in an initializer,safe_constantize
will create a recursive autoloading loop. We can hook intoActiveSupport::Dependencies
to check whether this is going to happen, and pre·emptively returnfalse
in that case (so that::Collection
is defined properly), without changing behaviour where::Collection
is gettingsafe_constantize
d from somewhere else.Fixes
