I hate to jump in so late to this already very discussed issue, but I'm 
going to have to add my voice to those against it.

I came to D from C/C++. If someone told me that D replaces #define with 
enum, I would have laughed in disbelief and then tried to define a bunch 
of 'static invariant' variables instead. It just seems so counter-
intuitive to use enum.
I should also add that more keywords is hardly a bad thing. Perl uses a 
quite large amount of keywords and nobody minds, because each keyword is 
generally given a meaningful name and a useful purpose. For example in my 
recent perl script I have the following line:
>"print "Couldn't get $url\n" and return undef unless defined $content;"
Six keywords on one line, and you could hardly say it looks confusing or 
ugly. I couldn't say the same thing for using enum to define static 
constants.

Please reconsider manifest, Walter.
