Does a patch that allows the clumsy idiom

already exist?

At what moment of time those "default expressions" would be evaluated?

At the moment of definition or at the moment of function invocation?

function pretty_print_time(unix_time=os.time())

Are they allowed to refer to each other?

function string.byte(str, from_pos=1, to_pos=from_pos)
