"SSAValue" syntax error parsing this keyword argument

[zot]

The last call to f in this produces a syntax error:

f(x; kw...) = println(x, kw)

f(3, u = 4)

tuple = (; Symbol("@/1") => (;
                             set = (; ref = 1),
                             metadata = (;
                                         type = "Main.PersonApp",
                                         create = :PersonApp,
                                         )
                             ),
     )

f(3, u = tuple)

f(3, u = (; Symbol("@/1") => (;
                             set = (; ref = 1),
                             metadata = (;
                                         type = "Main.PersonApp",
                                         create = :PersonApp,
                                         )
                             ),
       )
)

The error is:

ERROR: LoadError: syntax: invalid named tuple element "SSAValue(86)" around /tmp/tst.jl:16
