Hi Charles, thank you for your proposal. I think it could be an interesting addition. But rather than just a convenience function, make it behave more like its IO conterpart: IO.read/2
Where you can pass the byte length, or :line. Because sometimes is not about the bytes, but about the information held in a certain number of lines in the file. I'm thinking something like File.read(file_path, :line, 1) # or to read the first five lines File.read(file_path, :line, 1..5) I would like to know how the rest of the list feels about it.
