C# style params or python style *args in functions? (Did I miss this?)

Is there a model in Dart for saying "0 or more of this thing" in a
function def? Similar to "params T[] args" in C# or "*args" in python?

Did I miss it? Planned? Open issue?

Hi Kevin,

I found this old thread on varargs aka "rest params": https://groups.google.com/a/dartlang.org/group/misc/browse_thread/thread/d1c419a47b390fe8/88ee56369f9de7e7?pli=1

I didn't find an open language feature for varargs or rest params, so it's probably one of those "later" issues. Of course, if you have some compelling use cases, please do file a new feature request at dartbug.com for review in the future.

Thanks,

Seth

IIRC, Dart used to have those, but they were removed because they didn't play nicely with optional/named arguments. I hope they are coming back, sooner or later.
