So the bill of using pretty much anything in Phobos is pulling
in 87
modules. Pretty much what I feared it is.
There are several directions we can take this.
1. Improve the compiler to handle imports lazily, i.e. an
unused import is never opened. That's unlikely to help a lot of
uses because most unqualified name lookups require all imports
to be loaded (even after the name if resolved, the compiler
must still look for ambiguities).
2. Push imports from top level into the entities (functions,
classes etc) that use them.
3. Apply classic dependency management (break larger modules in
smaller ones, accept some code duplication etc).
I favor (2).

One of the
replys(http://forum.dlang.org/thread/[email protected]#post-heaeasepzokrwdsvytbe:40forum.dlang.org)
mentioned an
issue(https://d.puremagic.com/issues/show_bug.cgi?id=7016) that
blocks this solution.
