define should be the keyword for manifest constants

[Russell Lewis]

I thought about suggesting this, but what turned me off to it was this 
declaration:

	define int x = some_compile_time_func();

A C/C++ programmer will probably think of this as a #define-style 
substitution, which means that he will expect the function to run every 
time that he uses the constant.  However, what we are trying to declare 
is a manifest constant.  It seemed like it would introduce confusion.

Just my $.02,
