Same error message in v3.7.1 beta 9 (on Win 7)

But that construct is essentially the same as this (and the original #macro P()
can be commented-out, with no change):

#macro Q()
#local B = function { 0 };
#local B = 0;
#end
Q()

This throws the same error. So it appears that B can't be re-#local'ed there,
even though the 'new' B is not actually a new function.

However, this throws NO error...
#macro Q()
    #local B = function { 0 };
#end
#local B = 0; // or #declare
Q()

Strange. Although, in this case, the 'first' #local B to be 'processed' is
   #local B = 0;
which is NOT a function. So when B is then #local'ed again inside macro Q()--
only when Q() is INVOKED, apparently-- all is well.

BTW, there's no error at all when Q() is not actually invoked. That's
interesting; I thought your original code error might still appear, when POV-Ray
initially 'reads' #macro Q() in the SDL.

No error in my version either.
