Buggy interaction between @eval and delete_method #48802
Description
I could be missing something, but this seems bad to me:
julia> function track()
@eval function Base.getindex(A::Array{Int}, i1::Int)
println("A")
invoke(getindex, Tuple{Array, Int}, A, i1)
end
end
track (generic function with 1 method)
julia> function cleanup()
Base.delete_method(which(getindex, Tuple{Array{Int},Int}))
end
cleanup (generic function with 1 method)
julia> [1,7,3][2]
7
julia> track()
julia> [1,7,3][2]
A
7
julia> cleanup()
julia> [1,7,3][2]
7
julia> track()
julia> [1,7,3][2]
7I would expect to be able to resume tracking again after cleanup. I.e. the final output should also include "A". Replacing getindex with sin does not reproduce this issue.
