	  Agreed. If I understand correctly, the supporters of the former think 
it's easier to highlight and execute a subset of the earlier character 
string, e.g., "x |> f(a = 1)" than the corresponding subset of the 
latter, "f(x, a = 1)". I remain unconvinced.


	  For debugging, I prefer the following:


	  fx1 <- f(x, a = 1)
	  g(fx1, b=2)


	  Yes, "fx1" occupies storage space that the other two do not. Ir you 
are writing code for an 8086, the difference in important. However, for 
my work, ease of debugging is important, which is why I prefer, "fx1 <- 
f(x, a = 1); g(fx1, b=2)".


	  Thanks, again, for the reply.
