The libstrc pp-stratego-string strategy is unable to unparse the Override() AST node (as in the Stratego code override some-library-strategy = id).

This is a bit weird, since a PP rule for the override keyword appears to be present in all the Stratego(-Core,-Sugar).pp files I see.

See also this SPT test:

test bla
!AnnoDef([Override()], SDefNoArgs(“foo”, Id())); // <- can not be pp’ed
// !AnnoDef([], SDefNoArgs(“foo”, Id())); // <- can be pp’ed
//alltd(\Override() -> S(“override”)); // <- workaround
pp-stratego-string

Oh I see pp-stratego-string does not even use any PP table, it uses a custom transform to a BOX AST.
Which does not process the Override() AST node, indeed.

Added it. Probably need strc-java baseline update again before this is completely fixed.
