The parse time will invariably grow as phobos grows. I expect std.all
will become the preferred method of using D. The problems are:
1. People will come to expect std.all to have everything and the kitchen
sink in it, so we're stuck.
2. People will inevitably do compile speed benchmarks with std.all. And
then we'll suck.
So I say "no" to std.all.
I think there's no reason to become agitated. I measured compile time
with three imports and with std.all. The compile time with three imports
is 0.44s, and with std.all it's 0.82s. So we're talking about a very
small margin: 380ms.
Even if Phobos doubles in size (!), we're looking at meager increases in
compile time.
Also, let's not do the mistake of just taking one aspect of the problem
into account. std.all does have huge advantages, and the fact that we
can afford it will be noted and appreciated.
