Introduce "binding operations": generator expressions that evaluate a <body> once for each value they supply, with $<_0> expanding to that value. This is the foundation the $<LIST:TRANSFORM,...,APPLY> action and the predicate selectors build on, letting a <body> refer to the element being processed. Using $<_0> outside a binding operation is reported as an error rather than silently expanding to nothing. Issue: #27892
