If you create a file `config.nims` and write a line like `switch("import",
"sugar")`, you can write Nim code without writing `import sugar` under the
directory containing that `config.nims`.
I don't like adding nimpy as a built-in. I don't want to see I have to install
Python or Python related libraries when I install Nim even if I don't use
Python at all. Are there any problems that can be fixed only by making nimpy
built-in or standard lib? Are you sure making nimpy built-in or standard lib
really improve nimpy? I think doing so just make a illusion that Nim supports
Python FFI very well but can cause some problems or waste of disk space for
people don't use Python.
