If you import symbols explicitly, you'd have known.

Probably in your code:

     import std.file;

What should be there:

     import std.file : File, lines;

If lines is a member of the File struct, the import fails. If 
lines is not a member of File, not importing it fails. You get 
more detailed information.
Using import bind lists [1] usually is a good idea.
