Proposal: Collection Literals (original) (raw)

Given the possibility of confusion between set literals and array initializers, how much worse would it be simply to provide vararg constructors, in the various collection classes? Similarly, why not just some additional vararg factory methods in Collections that can be used to produce the immutable versions?

I realize that the syntax isn't quite as terse as what this proposal suggests, but I think it avoids the issues with reified types and would not represent a substantial deviation from the current state of the libraries.

The only place where this wouldn't work is for map literals; however, if a Pair literal were introduced as has been suggested elsewhere then this problem could be easily resolved.
