Does this lead to duplicate suggestions for, e.g., concrete types?

We should probably do this inference within get_type above.

thunk = context_module.eval(:(() -> propertynames($(ex))))
inf_params = Core.Compiler.InferenceParams(; assume_bindings_static=true)
frame = Core.Compiler.typeinf_frame(
Core.Compiler.NativeInterpreter(;inf_params),
first(methods(thunk)),
Tuple{typeof(thunk)},
Core.svec(),
true,
)

There are some ways available to perform inference on a toplevel expression directly rather than wrapping it in a temporary function and performing inference on it.
This piece of code from JET.jl might be useful:
https://github.com/aviatesk/JET.jl/blob/9f8add4ce3d8ba528249ec02023711759abb00d3/src/toplevel/virtualprocess.jl#L1395-L1415
(ignore the abstract_global_symbols! stuff)

if frame !== nothing && Core.Compiler.is_inferred(frame) && isa(frame.result.result, Core.Compiler.Const)
for field in frame.result.result.val
s = string(field)
if startswith(s, name)
push!(suggestions, FieldCompletion(t, field))
end
end
end
end
