Just to make this very clear to everybody reading this thread:
It's not even just that, but also the fact that we guarantee
API-, but not ABI-stability for Phobos. Every time we continue
to improve the pure/nothrow/@nogc situation by marking up some
more code, we are breaking the ABI, because the mangled names
of the involved symbols change. The ongoing work on `scope`
also breaks the ABI when enabled.
If you could change the SOVERSION with every one of these
changes, or simply just tie it to the respective Phobos release,
distributions would automatically do the right thing and compile
all D code using Phobos against the new version.
This might give Phobos a large soversion or and ugly one like
"2.074", but it would work.
(LDC's Phobos and GDC's Phobos already have a soversion set in
Debian...)
