+1 to @mg6maciej .

varargs

with size seems pretty obscure for deserving a language construct. Leave that at runtime.

cedric: I mean, if you look at it as the standard parser ops, we've got the optional operator

a?

in the form of "defaulted" arguments. We've got the kleen closure

a*

with

vararg

, it seems to me to be a natural extension to ask for the one-or-more

a+

operator.

@groos I think likening the

?

for nullable types to the quantity operator used in regexp is a bit of a stretch

I didnt mean nullable values are optional ones, I meant defaulted ones are optional ones
