Expand description

Prints to the standard error.

Equivalent to the `print!` macro, except that output goes to `io::stderr` instead of `io::stdout`. See `print!` for example usage.

Use `eprint!` only for error and progress messages. Use `print!` instead for the primary output of your program.

# Panics

Panics if writing to `io::stderr` fails.

# Examples

    eprint!("Error: Could not complete task");
