The output of the following function is strange.
Why is dbgPrint executed twice?
%%% (9) -> fooo(2)
Compiling function bar with type (Integer, Integer) -> List(Integer)
Compiling function fooo with type Integer -> Integer
[:> , ab, [1, 2]]
[:> , ab, [1, 2]]
(9) 2
Type: PositiveInteger
NB: If I replace the definition of fooo by
fooo(n: ZZ): ZZ == (_
n < 2 => error "argument must be > 2";_
l := bar(1, n);_
l.2)
the double execution goes away.
Anyway, maybe my assignment of variables inside a list "construct"
expression on the left-hand side is not conforming SPAD rules, but I
would expect the interpreter either to shout at me or not do the work
(function calling) twice. (Or maybe it is only output twice.)
Actually, why is it two times and not three times? It is a list of length 3.
