std_out (mixed message1[, mixed message2, mixed message3, ..., mixed messageN]) ⇒ string
Prints a message to the standard output of the system and returns the message. It also has infinite arguments which will be joined before printing.
Version 1.6.5 puts a space after each of the strings so
print("Hello", "World") will
std_out. Over time the functions will diverge in features and possibly syntax.
