[bikeshed] Syntactic sugar idea

[Joel VanderWerf]

This is a neat idea, but wouldn't it conflict with the "fluent
interface" construct? Using Joel's DSL example:

config "my window" do
.width @x
.height @y
end

if we changed it to

config "my window" do
.width calculate_width
.height @y
end

Now how does the parser know what .height refers to: calculate_width,
or the implicit block variable?

Yeah, seems impossible. Maybe if there were some other character instead
of "." to signify sending a message to the block's "default object".

But the fluent interface change *is* a parser change. My point was just
that seemingly trivial requests *can* make it into the core, whether
they're a syntax change or not.

Was that fluent interface syntax really a request? I cannot remember
anyone asking for it. I do, however, vividly recall various petitions
to *remove* that change.

It seems that often an object will be passed into a block only to invoke
a method of that object:
=A0 =A0arr.map{ |obj| obj.some_method }

So I had the (weird? stupid?) thought that it would be nice to have some
syntactic sugar like this:
=A0 =A0arr.map{ .some_method }

require 'enumerable/extra'

arr.mapsome_method)

Mmm losing the $ would then render RSpec completely inoperable since
it has an it method.

Forget the $ and you are spelling out a thought I was bearing with me
for quite some time, ty Daniel and Joel to bring this up .
I always wanted an implicit _ parameter in blocks, as e.g.
3.times do puts _ end

Cool! What would it take to make this 1.9 compatible?
