In a way this statement can be extended to the>
use of local variables. Still, as I said, it's
allowed. No need for "too ideological" approach
if that works for the programmer, neither for
insisting on "canonical" ways etc.
While many a stack op can be simulated using PICK and ROLL (hence
CS-PICK
CS-ROLL) I'm unaware of anyone using them in place of. If stack ops are
"canonical" it's because nobody has found a more efficient way of
programming
a stack computer. Recognizing this as the fact and the reality, a
programmer
that's serious will deal with reality and not chase after ideology which
is
the province of thought.
The stack ops THEMSELVES may be, in a way,
"canonical" — but not solving "each and every"
programming task using them "no-matter-what", IMHO.
