varargs vs collection-passing:

well I always have dreams about getting rid of stuff (so I can put in MORE OTHER STUFF)

If there weren’t objections to collection literals, what do you see are the other disadvantages vs varargs?

sure, although really I guess nonuniformity is 

[4, 5, 6]         // built in sequence
list.with [4, 5, 6]   // list 
set.with  [4, 5,  6]   // set…  

or with factory methods / non-dotted classes: 

[4, 5, 6]         // built in sequence
list [4, 5, 6]   // list 
set [4, 5,  6]   // set…  

or with one sort of magic:

collect [4, 5, 6]
collect [([4, 5, 6 ])] 
collect [{[ 4, 5, 6 ]}] 

or another sort of magic

[4, 5, 6]
[([ 4, 5, 6 ])] 
[{[ 4, 5, 6 ]}] 

which do we prefer?
