You need to pass in the type of the argument, not the argument itself,
to methodswith
julia> @enum FRUIT apple=1 pear=2
julia> methodswith(Type{FRUIT})
5-element Array{TypeMapEntry,1}:
convert(::Type{FRUIT}, x::Integer) at Enums.jl:79
instances(::Type{FRUIT}) at Enums.jl:86
typemax(x::Type{FRUIT}) at Enums.jl:83
typemin(x::Type{FRUIT}) at Enums.jl:82
