This is on Julia master and Cassette#master.

Example 1

julia> using Cassette

julia> Cassette.@context Ctx
Cassette.Context{nametype(Ctx),M,T,P,B,H} where H<:Union{Cassette.DisableHooks, Nothing} where B<:Union{Nothing, IdDict{Module,Dict{Symbol,Cassette.BindingMeta}}} where P<:Cassette.AbstractPass where T<:Union{Nothing, Cassette.Tag} where M

julia> function Cassette.overdub(ctx::Ctx, f, args...)
           if Cassette.canrecurse(ctx, f, args...)
               Cassette.recurse(ctx, f, args...)
           else
               Cassette.fallback(ctx, f, args...)
           end
       end

julia> function foo()
           rand()
       end
foo (generic function with 1 method)

julia> Cassette.@overdub Ctx() foo()
