scoping blocks in octave code?

[fork]

Hi all,

Is there a way to limit the scope of variables in a stretch of code?  This can
be useful with temporary index variables in for-loops, but it can be nice in
many other contexts (though one should probably be more aggressively putting
stuff into functions if this kind of housekeeping becomes necessary).

I don't think this is possible, but I was happily surprised with the support for
closures and subfunctions so I thought I would ask....

I *think* in newer versions of C, if you declare a variable inside a block, that
variable goes out of scope at the end of the block. Schematically:

begin
    for myind = 1:10
         blah += myind
    endfor
endbegin

## now myind would be gone
