Yes there is.
Rainer Schuetze is quite close to a solution. Which reduces the
symbol-name bloat significantly.

That's very nice. Hope we will get this through sooner rather than
later!
I'm super-psyched this has moved from "proof of concept" to ready for
review. Kudos to Rainer for his work on this! Has been a PITA for a while:

In any case, I think the actual compilation times would depend on the
details of the code. If you're using relatively shallow UFCS chains,
like Phobos unittests tend to do, probably the compressed symbols won't
give very much advantage over the cost of computing the compression.
But if you have heavy usage of UFCS like in my code, this should cause
significant speedups from not having to operate on 300KB large symbols.
I have found that the linker gets REALLY slow when the symbols get
large. So it's not necessarily the compiler that's slow for this.
