When I last used KQL, it was infuriating that I could create my `let` clauses in chunks separated by whitespace because a blank line would be considered a terminated statement (and Kusto would say "Hey where's your expression?!"). This meant every Kusto file was a sea of text with no clear differentiation between subsequent clauses. I ended up using 3 blank comment lines as a "fake empty line" just to maintain my sanity.
Again, hope they fixed that by now...
