I don't know. It probably makes sense for some stuff, but in 
other cases, the fact that it ends up in a module other than its 
target module could be problematic (especially when overloads 
come into play). It also seems like extra red tape and extra 
effort that's then going to have to be spent moving symbols 
around. On the other hand, it would at least potentially help 
catch some problems.

Regardless, we need to make it clear how we're going to move 
stuff from std.experimental to std, and what the timetable for 
that is supposed to be. AFAIK, thus far, we've never moved 
_anything_ from std.experimental to std. In the case of new 
modules, are we supposed to vote on them again before actually 
moving them into std? Do they just get moved over after they've 
been around for a certain period of time? Or is it some other 
criteria? And if we start putting new symbols in 
std.experimental, should those same criteria apply to individual 
symbols in addition to modules? Having another vote before 
migrating a new module might make sense, but that's definitely 
overkill for a new symbol. And new symbols probably don't need 
the same kind of bake time that a new module would. Right now, 
AFAIK, we have no policy with regards to std.experimental at all 
except that that's where new modules are supposed to go when they 
get voted in.
