[TxMt] non-blank-lines block as scope to eval

I'm using TextMate with OCaml extensively, and use an Eval script from Johan Kullbom to send either a selection or a current line to an iTerm with ocaml interpreter in it (adapted from F#):

The problem is, OCaml grammar doesn't really show functions properly, fold-unfold handles make no sense. Thus, I have to select a function manually if I want to send it to ocaml.

Now I chose "Line" in Input: [Selected Text] or [Line], but what I'd really like to choose is "Non-blank line segment around the cursor". I'm not sure what can I do with the [Scope] there, as scopeName defines the whole 'source.ocaml', AFAICU.

So, is there a way to achieve "select Non-blank line segment around the cursor, then send THAT to ocaml using an Eval snippet or similarly"?

Cheers, Alexy
