" We call it "logic-less" because there are no if statements, else clauses,
or for loops."

... except that to accommodate the people who actually do require these
things in their views, we've invented *our own* constructs for
conditionals, iteration over a list, and function call - it's just that
they use special-purpose syntax you'll have to learn separately

Or am I reading it wrong?  And what's so great about logic-free anyway?
Get business logic out of views, by all means, but there's nothing shameful
about putting the "if there are no results, display 'no results' instead of
an empty table" logic in the presentation layer - that's exactly where it
should go imo.  The model certainly shouldn't be responsible for knowing
how the UI should present an empty set

Sorry if that reads like flamebait.  Must drink more tea
