Actually the difference is one of 'operator precedence' and not one of
scope, as far as {} can be called an operator. {} just binds very thight
to the call to bar, whereas do end binds loosely to the call of foo.
This means that

~  puts str.gsub { ... }

will do what you expected but

~  puts str.gsub do ... end

will call puts with a block. Hence the single line/multiline difference.

Thank you for your OT (not to me) pointers, I will put them on the list
of things to
read ! Perhaps you will be interested in my opinion afterwards ;) ?
