	For B) I suppose you suggest something like:

#declare t1=texture{... transform ...}
#declare t2=texture{... transform ...}
...
mesh{
  triangle{ ... texture{t1} }  // or smooth triangle
  triangle{ ... texture{t2} }
  ...
}

which of course requires a lot of memory to declare both texture variables
and textures in the mesh. But what about the following syntax ?

mesh{
  #declare t=texture{ ... transform ...}  // #local is more elegant ?
  triangle{ ... texture{t} }
  #declare t=texture{ ... transform ...}
  triangle{ ... texture{t} }
  ...
}

which might be only a little longer to parse... maybe not.

	In case you were talking about this syntax, please ignore my post !
	BTW declaring UV vectors with XYZ should change the mesh2 syntax ;-)
