That's certainly presumptive, at best. You don't write every function
you use, you don't use every value a function returns (system_exec?),
and many functions do MORE than just return a value.
If you don't want to use the value a function returns... you can currently =
do:
global object JUNK
...
JUNK = myfuncwithignoredreturn()
--...Great, every time I call this, it has to de-allocate the data
that was previously stored in JUNK, allocate space for the return
value, and set it, for nothing.
Or you can do:
if myfuncwithignoredreturn() then end if
--...Why the hell would we use a control structure for no reason? Not
to mention the fact that this crashes if the func returns a sequence.
There's still overhead too - the interpreter has to store the return
value long enough to calculate whether it's zero or not, and the
comparison has to be done.
I used to think that the language having a procedure call and a
function call was quite logical, but after becoming acquainted with
plenty of other languages, I'd say it's a rather useless feature.
