Operator Names

What is this ‘=>’ operator called?

Does it have a name?

From my Perl days, I learned to pronounce this “is” although I don’t
know if it has a true name.
(Try it next time you’re reading code with a hash.)

I believe it’s called a “hashrocket.” At least that’s what the guys
and gals at http://www.hashrocket.com/ would have me believe.

Read my books:
Ruby in Practice (http://manning.com/mcanally/)
My free Ruby e-book (http://humblelittlerubybook.com/)

Or, my blogs:

I read it as “points to”

I always read it as “goes to”,

but in the Rubinius core, they define the following stuff…

rubinius/lib/ruby-token.rb:197

[:TkLSHFT,      TkOp,   "<<"],
[:TkRSHFT,      TkOp,   ">>"],
[:TkCOLON2,     TkOp],
[:TkCOLON3,     TkOp],

[:OPASGN, TkOp], # +=, -= etc.

[:TkASSOC,      TkOp,   "=>"],
[:TkQUESTION,   TkOp,   "?"],   #?
[:TkCOLON,      TkOp,   ":"],        #:

ie. TkASSOC

One of my Ruby books describes it as “the sequence of characters” in
the context of a Hash explanation.
