Arrays / collections with literal syntax - fixed size?

Are #(...) and {...} the only 2 short, non-message-passing syntaxes for 
creating collections?

They both seem to yield Array, which apparently has a fixed size. I'm 
curious about why the only (I think) convenient syntax for simple collection 
usage has this restriction on what you can do with it.

And as far as I can tell, there is no similar convenient syntax for 
dictionaries. Is that true?

I am trying to build up some simple declarative meta-data structures and 
find a big jump in verbosity from simple syntax to constructing things by 

Thanks - Sophie
