[dmd-internals] Changes for pure, nothrow, and @safe done for the moment?

[Jonathan M Davis]

Walter, are the changes that you've been making to pure, nothrow, and @safe in 
dmd essentially done for the moment? Or are there still more to come? They've 
reaked some level of havoc with Phobos (for better or worse), and so assuming 
that all of the changes that you've made are valid, some changes are going to 
need to be made to Phobos so that the unit tests will compile again, but I 
don't see much point in trying to sort any of that out if you're still in the 
middle of making big changes.

Regardless, I'm particularly stumped by the errors in std.concurrency. It 
seems like the combination of purity and nothrow inference and making the 
compiler complain about calling pure nothrow functions without using the 
result is breaking it (certainly, I don't see any pure nothrow functions in 
there anywhere, so I have no idea how else it could be complaining about pure 
nothrow functions having no effect). So, I don't know if that's a compiler 
issue or an issue with std.concurrency. But I don't want to try and fix 
anything yet if you're still making big changes.
