── TYPE MISMATCH ───────────────────────────────────────────────────────────────
Something is off with the body of the `myDict` definition:
1│ myDict : Dict I64 Str
2│ myDict = Dict.insert Dict.empty "foo" 42
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This `insert` call produces:
Dict Str (Num a)
But the type annotation on `myDict` says it should be:
Dict I64 Str
"#
),
)
}
}
