Sure, it would be a coincidence, if both will work. However,
templates are not something where you can simply imply the
associative property, I think.
Of course there isn't an associative property... But I was thinking
that without brackets the parser could fall back to whatever default
"left to right" precedence, as would happen with operators, which
needn't be associative either.
Ah... ok. Got your idea. No. This isn't possible because some symmetry
of the operator is implied.

Chaining is explicitly not allowed, like in comparison operators :)
Note that Instantiate in std.meta exists to overcome this limitation:
Instantiate!(foo!bar, x);
