Function local imports make it easier to reason about the code which is of slight importance. The big thing I'd like though is using it with mixins.
In my cgi.d, there's a mixin main that depends on std.string being available inside the mixed in function. Currently, I use a public import of std.string. Alternatively, the other module could import it too, but that is pretty opaque. But a scoped import would be cleaner: I could ensure it's always available in that function without making the mixin user wonder WTF the error messages are about and without polluting his namespace.
