Support IE < 9

[wolverian]

do is an invalid identifier in IE < 9:

>>foo.do = function(){}
  "Expected identifier"

foo["do"] does work.

Yeah. I'm sorry about this, I really should have mentioned it at least in the readme.

BEGIN Mumbling into internets

Long story short: I was aware of this when writing zhain. Also, my current project didn't/doesn't need to support IE < 9. I thought long and hard about valid, working synonym, and since I couldn't find a word concise and relevant enough, I gave up and blatantly decided to let legacy-IE-people suffer. Sorry about that, it was my laziness.

Suggestions for an alias are welcome. Here's what I've thought of:
.ex() - as in execute
pow() - as in a meaningless word and therefore understandable only through documentation
go() - you know, as in "go do this"
z() - as in, well, "zhain it", I suppose

Not really happy about any of them. .do() is a word that matches what's going on in a nice way...

Oh, and there's of course also the option to forget about the .do altogether, and write something crazy like this:

zhain()
  (function() { console.log('what up?') })
  (function() { console.log('... homeboys') })
  .run()

But I feel it might scare people ;)

How important is this for you?

The parens-only syntax seems pretty sweet. Any non-feelings based reason for not using it?

Just my two cents

It wouldn't fit CoffeeScript very well, I think:

zhain()
  (-> foo)
  (->
    bar
    quux)
  .end()

vs

zhain()
  .do ->
    foo
  .do ->
    bar
    quux
  .end()

The latter is much more idiomatic.

• Bacon uses doAction.
• then might work, though it does overload what Promises/A+ means with then.
• z is pretty nice.

One unrealistic option would be to change all uses of .do in Zhain to ["do"]. This is what CoffeeScript compiles .do accesses to, so if you wanted to use Zhain with IE < 9, you'd have to use CoffeeScript, or write ["do"] everywhere yourself.

I'm not convinced. If I don't get a djuizzy zhain(foo)(bar)(baz)() syntax, imma fork!
