compiler/det_report.m:
... when a "declared det, inferred multi" kind of determinism error
is caused by the (probably unexpected, possibly hard-to-see) presence
of a disjunction.
Change the wording to refer to "disjuncts" instead of "clauses";
while in Mercury, all clauses in multi-clause definitions are implicitly
also disjuncts, not all disjuncts are whole clauses.

not_a_switch.m:014: In `not_a_switch'(in, out):

|
not_a_switch.m:014: error: determinism declaration not satisfied.
|
|
not_a_switch.m:014: Declared `det', inferred `nondet'.
|
|
not_a_switch.m:014: The reasons for the difference are the following.
|
|
not_a_switch.m:019: Disjunction has more than one disjunct with solutions.
|
|
not_a_switch.m:021: Unification of `A' and `maybe.yes(Int2)' can fail.
|
|
not_a_switch.m:022: In argument 1 of clause head:
|
|
not_a_switch.m:022: unification of `HeadVar__1' and `maybe.no' can fail.
|
|
not_a_switch.m:022: This later disjunct may have a solution.
