For me it's a good message.
Messages like this were an annoyance when I started out. If you don't
import std.stdio, you get the error message
Error: 'writeln' is not defined, perhaps you need to import std.stdio; ?
That's a very helpful error message if you're new to D, and especially
helpful if you're new to programming. This particular error is likely a
common one, and adding "perhaps you need to import std.conv" would help
a lot. Even a generic "perhaps you forgot an import statement" would
tell new users what the error might be. Making it worse is that it says
core.time.to but there was no import of core.time.
How do compiler know that you want use `std.conv.to` instead of _already
imported_ `core.time.to`? In general it's impossible. There is no way
for compiler to guess that you want some other symbol from out there.
What if you've imported `std.conv.to` but want to use `core.time.to` -
what should compiler do in this case?
What about `writeln` - it's too different.
