Yup.  I simply find it troublesome that /conventions/ in C/C++ are being 
used as justification for new language features in D.  For programmers 
new to D who do not have a C/C++ background, I'm not sure I'd want to 
resort to a history lesson when asked why 'enum', which is short for 
'enumeration' is used to signify manifest constants.
