Thank you.

This was a bug waiting to happen.  Commit 7d69d4a61b happened to change
the order in which keys came out of %::.  So Parse::Trace, which goes
iterating through the stash looking for a variable containing $self (for
verbose output), happened to stumble across $^V, which has explosive
overloaded methods.  (I think version objects are very un-perlish in

So it looks as though ParseLex needs to work around this, otherwise it’s
just by chance that it passes its tests.
