OK, I signed up to the issue, but there seems no way of voting for it to
try and raise its chance of being fixed.
Despite my personal dislike of this use of string to write functions, I
can live with it in this case, so I am not worried about a workaround in
std.parallelism -- though a DMD fix would be good.
Thanks.
