> because it's used in a UNION:
Let me see if I've got this:
?entity hasAnInstrument "Trumpet"
{ BIND(?entity AS ?s)}
UNION
{ something }
The union groups two things, so we're connection the output of the
BIND to the output of the something.
If I wrote:
{ ?entity hasAnInstrument "Trumpet" . BIND(?entity as ?s)}
UNION
{ something }
... drat. I just don't get it. I tried reading the LET description
from ARQ, and I still can't explain it. There's manifestly something
very fundamental to how the pieces of the query go together that I'm
just not understanding.
