Another form of goto

[David Herron, NPR Lover]

I came up with the following piece of C code the other night.  A friend and
I were talking about ways of writing a generic Forth interpretor in C.
We realized that the register save/restore at procedure call cost a lot
when you have lots of small routines (as in a forth interpretor).  Also,
a large switch statement has expenses of its own.  Then we thought about 
indirect goto's.  et voila:

	main()
	{
		int *a;

	b:
		a = b;
		printf("a = 0x%x\n", a);
	}

(NOTE: This was compiled under 4.2BSD on a -750)

This compiles and runs perfectly.  However, when adding an obvious statement
(namely, "goto *a") it won't let us compile it.  It seems like the compiler
will *almost* let us do this.

What I want to know is, "can this be easily added to the language?",
"Is it a reasonable thing to add?".  Comments anyone?

No stupid sayings (I can't think of one).

No stupid disclaimers (Nobody else would claim my statements anyway).
