I'm expecting anyone would be in favor of various improvements
to our online documentation.  Perhaps if you begin such a 
document....? :)

The print version of Programming Ruby has a truly impressive and
useful index.  In it, you'll find:

  {...}
    hash literal 11, 206
    in pattern 61, 209
    see also Block

Or.... never underestimate IRB:

irb> {}.class
Hash

Aha!
