Just recently the following problem arose. I have a macro and I want
to pass to it another macro as a parameter. The problem gets bigger as
I don't know the second macro's number of parameters. So if I have
macros A, B and C, I want to do something like

#macro A( vector, float, string, B)
  #local variable = B;
  C(variable)
#end

and then invoke it in this (or similar) manner:

#declare another_variable = 
A( <1,3,1>, 5.34, "3455sdf", function(clock*clock + 1));

Is this possible at all?

Peter
