-When a regular expression is compiled that contains user-defined properties,
-the subroutine the user must furnish to implement those properties may not yet
-be defined.  To cope with this possibility, the regex pattern compiler stores
-the name and package of the subroutine, and this is to be expanded the first
-time the property is actually used during execution.  Once expanded, the
-property should be immutable, and so the scalar containing the expansion is
-marked read-only.  It turns out that prior to the blamed commit, that
-read-only-ness was being bypassed in some instances simply by freeing the
-scalar, replaced by a new one.  The commit changed that.  The pattern may
-contain components both known at compile time, and deferred until runtime.  The
-two are combined at the time of expansion, but that was now running afoul of
-the read-only setting.  This commit simply turns off the read-only flag at the
-time of expansion, and it's turned on again afterwards.
+This involved user-defined Unicode properties.
