[ruby-core:41854] another YAML problem: read-write cycle messes up human readability

Out of desperation, I am currently storing data lines like

- 0 3 2 8 3 1 12 7 4 28 4

i.e., an array of int's stored as a string,

which is against the spirit of YAML, since the obvious
way to store such data is a true array,

- [0, 3, 2, 8, 3, 1, 12, 7, 4, 28, 4]

However, when writing this data structure by means of
an official YAML emitter, I get

- - 0
   - 3
   - 2
   - 8

and so on,

which for my purpose (many such lines) destroys all
the human readability that makes YAML so attractive.

Is there any way to instruct the YAML emitter to write
certain arrays "in line"?

Or any hope that such feature will be added?
