I completely agree, and this is something I'd like to improve when we
overhaul the build system.
I've been largely ignoring messages about perceived deficiencies in the
current build system, given the consensus is to replace it anyway, but
it seems to me that it has gotten better, not worse, in this respect.
Almost all generated files are now put in dist* directories, which makes
them easy to clean; and even if you do stop using a dist directory and
it doesn't get cleaned, it's hard to see how files in such a directory
could interfere with the build.
Ah, there I wasn't referring to the problem of old build droppings
upsetting the build, but to the fact that we always need to clean the
tree and do a fresh build (they are related, of course). You're right
that the build system is doing better at keeping all its generated files
together now, and we'll keep doing this when we change the build system.
We can do much better than we currently do at tracking dependencies,
particularly between libraries.
Cheers,
Simon
