Removing the declare would be very difficult from the standpoint of the
parser since, if you have a variable by itself, POV interprets it as a
float identifier and not an assignment statement.  However, maybe a shortcut
like just putting a special character at the beginning would allow the parser
to know that it is an assignment. (like maybe a '%'.  Is that used elsewhere
in POV?)  Then you would use
  %e=i*2;
instead of
  #declare e=i*2;
and the compiler would still know what you're talking about.

I also still think we should always be able to redeclare anything as any
other type (maybe warnings should be issued, but not for float -> vector
conversions).
