I assume you mean method syntax.  But why is that important?  Until
this new syntax was posted, I'd never heard anyone complain that they
found it hard to recognize {|...| } as a code block.  Now there seems
to be a retroactive sentiment in the air that the block syntax is, and
always has been, obscure or garbled.

If uniformity is important maybe def should be redesigned:

   def x |a,b,c=1|
   end

Then you'd have parallels between blocks and methods:

   def == {
   end == }
   || == ||

without the -> thing.
