Hi,
If f is a dyad, then
f/ 2 4 5
means
2 f 4 f 5
where the rightmost occurence of f is invoked first. I am wondering if
there is a smart way to recognize this first invocation separately from the
rest. This will enable me to perform some initialization inside f. By
"smart" I mean something smarter than the followung two:
1) using side effect like setting a global flag.
2) adding some signature structure to the output of f (eg, 'inited';
result),
and then checking the absence of this signature.
Thanks.
