The non-block looping constructs: while, unless, for/in do *not*  
create a new scope.

The block looping constructs: each, loop do create a new scope.
The scoping behavior exists because of the block, not because the
methods each or loop have some special properties.

So basically your question is about blocks, not about loops.

Matz has acknowledge that the behavior of block arguments and block  
local variables
is confusing and is exploring some alternatives.

See Austin's post for an illustration of the current behavior of  
block arguments and
local variables within a block.
