     PATCH: [perl #133860] 5.30 regression
     These bugs stem from trying to compile a user-defined \p{IsProperty}
     before the data for the property is available.  In the past, a bug used
     the wrong package for IsProperty, and it wasn't found, so its expansion
     was delayed until runtime.  But that bug got fixed, and now it finds the
     property and thinks its deliberately empty, at compile time.
     This is a change in behavior, even if it is fixing a bug, where the real
     problem is unobvious.  The solution adopted in this commit is to defer
     all empty properties at pattern compilation time.  If they are still
     empty at runtime, that's what the expansion will be.
