some do, but sometimes redefinition is quite legal; it happens that 
'note' and 'symbol' are pretty core

the convention (as mentioned) is more or less to use UpperCase names for 
your own commands and UPPERCASE for logo's and abbreviations (but these 
can have an optional namespace)

kind of tricky are colors and fonts as they have no namespace so i often 
end up with ThisColor or ThatFont

maybe later, as it clutters the code; maybe after the mkii->mkiv cleanup
