chapel-users/developers,
found a small issue and was unsure if this is an expected or unexpected
feature.
::variable arguments, tuple expansion::
proc callb(kargs...?k) {
writeln(kargs);
}
proc calla(kargs...?k) {
writeln(kargs);
callb(kargs);
}
calla(1,2,3);
the output is:
(1,2,3)
((1,2,3))
at the moment, i can "sort of" hack around this issue by expanding the
kargs tuple prior to calling callb in the function calla
proc calla(kargs...?k) {
writeln(kargs);
callb((...kargs));
}
:: params use ::
when passing particularly complex, non-homogenous tuples into kargs
(example: calla((1,2), (3, "cat"))) are there best practices?
i've a program in which the kargs tuple going into calla needs to be passed
around to several smaller functions in calla and there have been a couple
occasions in which the compiler will claim "error: invalid access of
non-homogeneous tuple by runtime value" or "Types.chpl:356: error: Function
'isHomogenousTuple' has been instantiated too many times note: If this is
intentional, try increasing the instantiation limit from 256".
in these cases, i've had some success annotating the value used to index
kargs a param.
thanks!
