I proposed:

This bug seems to have slipped off the radar, because it has been classified as
"editorial". But I think it's too substantial to implement without consensus.
Could we have it back on the agenda please?

The operators "is", <<, >>, "union" (= "|"), "except", "intersect", "to", and
"," are defined in two places: in the language book, and in F+O. There is no
statement as to which description is definitive. F+O claims that its
descriptions define the semantics of the operators defined in the language
book, but the language book contains no reference to the F+O definitions, other
than a mention in the operator mapping table. The language book contains
complete (though somewhat informal) free-standing definitions of the operators.
The F+O description does not say how empty sequence is handled as an argument;
this is explained only in the language book. None of these operators have any
associated error conditions.

Unless anyone objects, I propose that we delete these 8 operators from F+O, and
remove the corresponding 9 entries (plus "||") from the operator mapping table.

The WG accepted this proposal.
