Hi,

1) Adding a 'toclose' variable in the 'for' loop is an undesirable
feature in my opinion. Not aware of any language that does that.

2) With regards to the 'toclose' variable declaration, introducing a
'with' statement is the nicest approach.

with <vars> = <initializers> do

end

This idiom is familiar to most programmers who use Python.
BTW @Patrick Donnelly this has nothing to do with Python's reasons for it etc.

3) Finally I feel the 'const' feature can be omitted so that leaves
only one syntactical addition as above, and gets rid of the issue of
annotations for now.  (I am for a generic annotations capability but I
feel it isn't a good fit here - I agree with Daurnimator on this
point).
