Thanks, I've found the culprit. There's been quite a few changes in the import graph upstream. This looks to have exposed some unfortunate template emission bugs in older versions of the compiler that as you've pointed out, work just fine with gdc-11. I'm err'ing on the side of reverting the individual patches, though if I get time later, maybe try a partial revert by restoring the old import statements only. Iain.
