Even trivial @report_opt calls fail (at least with nightly Julia).

julia> f() = 3
f (generic function with 1 method)

julia> @report_opt f()
ERROR: MethodError: transform_result_for_cache(::Core.Compiler.AbstractInterpreter, ::Core.MethodInstance, ::Core.Compiler.WorldRange, ::Any) is ambiguous.

Candidates:
  transform_result_for_cache(analyzer::JET.AbstractAnalyzer, linfo::Core.MethodInstance, valid_worlds::Core.Compiler.WorldRange, result::Core.Compiler.InferenceResult)
    @ JET ~/.julia/packages/JET/wMeAT/src/abstractinterpret/typeinfer.jl:442
  transform_result_for_cache(interp::Core.Compiler.AbstractInterpreter, linfo::Core.MethodInstance, valid_worlds::Core.Compiler.WorldRange, result::Core.Compiler.InferenceResult)
    @ Core.Compiler compiler/typeinfer.jl:353
To resolve the ambiguity, try making one of the methods more specific, or adding a new method more specific than any of the existing applicable methods.
