But in

	let{a:=1; b:=2; obj.meth(a).meth(b) do ... end }

a and b are locals before I want them to be locals... I want them to be
locals in the iteration only. Yes, I don't know if it's useful, I am not an
expert programmer and sometimes lack some common sense ;).

By the way, it will be

	let{ ... }  and  let ... end

or how?

Well, like others proposed too, the idea is to have a header for the block
that could be used to initialize variables. Like the first part in a
for( ; ; ).

	5.times let p:=list do p p; p=p.next end
or

	5.times let <p=list> do p p; p=p.next end

The only benefit is that it avoids excesive nesting... I use tabs for
indenting ;).
