strange Variant bug...

[Lloyd Dupont]

Hi Andrei,

Thanks for the quick fix and work around! :)

Mm.. unfortunately Variant.init can be on either side of the equality, 
depending on the circumstances...
I'll have to learn how to get the latest D compiler from the sources.. :~
Is there a wiki HowTo somewhere?

Sorry. Fixed in
https://github.com/D-Programming-Language/phobos/commit/ee5c3a39e55bc39d49fc46aed9b2c81cccdb4122.
This gave me the opportunity to also fix a not-yet-released bug that
would have been embarrassing - bool true and false would have been
printed as characters 1 and 0.

Feel free to patch your installation. A workaround is to reverse the
order of comparisons if you know the right-hand side is always initialized.
