Actually array() is from sts.array and correct way to use
selective imports is:

If you want to import several symbols from one module, you can
list them after the column like so:
import std.algorithm : any, find, sort /*, etc... */;
I hadn't compiled yet, so the array thing is indeed an error.
So there's no way to combine these _selective_ imports on a
single line, like I can with regular _module_ imports:
import std.exception, std.array, std.functional;
Correct?
Yes, it is not allowed by the grammar. I think the reason is that
the list items would become ambiguous (the difference between
selected symbols and module names could only be revealed after
semantic analysis). See for example:
import abc : cba, dcb, bca : acb, dbc;
// What is dbc? A module or a member of bca?
