new syntax sugar for anonymous objects

[yegor256]

Consider this code:

malloc.of
  100
  [m] >>
    QQ.io.stdout > @
      m.read 0 10

It would be more convenient to write it shorter:

malloc.of 100 [m] >>
  QQ.io.stdout > @
    m.read 0 10

This will save one indentation.

@maxonfjvipon WDYT?

@yegor256

1. Looks like a mixing of a vertical and horizontal notations in application
2. It's hard to understand if >> should be applied to anonymous object or whole application

[yegor256]

@maxonfjvipon indeed, it's a mix of notations. How about this instead:

malloc.of 100 [m]>>
  QQ.io.stdout > @
    m.read 0 10

Which is very close to what we do in Ruby:

malloc.of 100 { |m|
  puts "hello"
}

[maxonfjvipon]

@yegor256 better, but still... if we allow the mixing in such case, it'll be possible to write something like this:

sum 1 2
  3

We prohibited on purpose some time ago

[yegor256]

@maxonfjvipon we won't allow this, just one special case, with the [...]>> at the end

[maxonfjvipon]

@yegor256 ok, I'll try to introduce it into our grammar

[maxonfjvipon]

@yegor256 I see one more problem with this syntax:

malloc.of 100 [m]>> > @
  true > @

This [m]>> > @ looks weird and a bit confusing. WDYT?

[yegor256]

@maxonfjvipon I don't think we should allow anything after >>. Only EOL.
