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.
