For engineering reasons I really like the fact that you can always find
the definition of any name by simply looking in the same file. Any name
"foo" is always:
1. Defined in the same file.
2. Imported at the top of the file.
3. Defined in the prelude.
For large projects, this eliminates a lot of grepping through the codebase.
