The way to not affect other components is to keep your namespace
clean/consisitent and as Alain said, choose some standards like always
orienting things a certain way.  So if you have multiple nosecone types, if
it were me I'd do something like #macro NoseCone_Type_1() rather than
NoseCone()  Still, objects that have already been placed in a scene won't
be deleted even if their names get overwritten.

You can always put one macro per include file as some people (not myself)
advocate.  #ifndef() is very handy for checking to see if something's been
included already or not.
