Proposal: Collection Literals (original) (raw)

Hi Josh,

This would be a very nice feature to have. One small nit:

By substituting curly braces for the square brackets, you get a set literal

in place of a list:

final Set primes = { 2, 7, 31, 127, 8191, 131071, 524287 };

The literal syntax is the same as for an array initialisation, which could cause a bit of confusion. In the example - for example :-) - it looks like an array of ints is being autoboxed into a set., but I presume that won't actually be what happens (i.e. the assignment wouldn't compile if the literal was replaced by a variable with type int[])?
