Description:
------------
I believe the dollar sign in variable names to be a waste of precious keystrokes, 
and I would boldly suggest the requirement that variable names be prefixed with a 
dollar sign is removed. 

Currently, undefined literals are interpreted as strings (with a "Notice" fired). 
This is a hardly useful feature, as most useful strings will contain spaces. A 
better use of such tokens would be to interpret them as variables.

If this feature would not be seriously considered, I would appreciate any pointers 
into the relevant source code location(s) that needs to be modified to implement 
this feature.

Thanks,
AhmetSacan.
