Description: Creating a Rumpelstiltskin character who is always referred to as "dwarf", "guy", "dude", or "man" -- depending on which the player last used -- until the first time the player refers to him as "Rumpelstiltskin".
For: Z-Machine

	{*}"Straw Into Gold"

	The Cell is a room. Rumpelstiltskin is an improper-named man in the Cell.  Rumpelstiltskin can be identified or unidentified. Rumpelstiltskin is unidentified.

	R-name is a kind of value. The R-names are dwarf, guy, dude, and man-thing. Rumpelstiltskin has an R-name. Understand "[R-name]" as Rumpelstiltskin.

Our example is slightly complicated by the fact that "man" is a name already known to Inform, so we can't re-use it as a kind of value. This is possible to work around, though:

	{**}Understand "man" as man-thing.

Now we borrow from the Activities chapter to look at the exact wording of the player's command:

	{**}After reading a command:
		if the player's command includes "[R-name]",
			now the R-name of Rumpelstiltskin is the R-name understood;
		if the player's command includes "Rumpelstiltskin":
			now Rumpelstiltskin is identified;
			now Rumpelstiltskin is proper-named.

	Rule for printing the name of Rumpelstiltskin when Rumpelstiltskin is unidentified:
		if the R-name of Rumpelstiltskin is man-thing:
			say "man";
		otherwise:
			say "[R-name]".

	Test me with "x dwarf / x guy / x dude / look / x rumpelstiltskin / look / x man".
