As you probably read (agreed, notes are strung out and not 
well-indexed), we considered that too. It fell to the objection that 
users certainly want const and class declarations from one script to be 
usable in subsequent scripts. For let, we didn't want to break symmetry 
with const and class at top level (if you want per-script let, use a 
block around the whole script body).
