and
	5.times do |;a| a=gets; print a end
or
	5.times do <;a> a=gets; print a end
?

Both are very ugly ;)

I think parameter passing and locality (?) of variables should be handled
orthogonally. Maybe adding a new keyword.

I can think (uh... these are very ugly too):

- extending the block syntax to optionally predeclare local variables:

(1..10).each usinglocals :a, :i do |i| a=i*i end

- adding a keyword to declare a local variable:

(1..10).each do |my i| my a; a=i*i end

- the same, but postdeclaring (?) the parameters as local:

(1..10).each do |i| my i, a; a=i*i; end

I'd prefer a little more verbosity than more special symbols and dangling
semicolons and commas...
