I like
"test-vgc.d(9) vgc[CONCAT]: (a ~ b) causes gc allocation"
a lot more than
"undefined reference to gc_alloc" ;-)

I posted a proof of concept pull request here:
https://github.com/D-Programming-Language/dmd/pull/1886

It needs some work but maybe it will be ready for 2.063. Would be
great if both of you could comment there as you probably have most
experience in avoiding the GC :-)
