(reader x & opts)
Attempts to coerce its argument into an open java.io.Reader. Default implementations always return a java.io.BufferedReader. Default implementations are provided for Reader, BufferedReader, InputStream, File, URI, URL, Socket, byte arrays, character arrays, and String. If argument is a String, it tries to resolve it first as a URI, then as a local file name. URIs with a 'file' protocol are converted to local file names. Should be used inside with-open to ensure the Reader is properly closed.
