ambiguous soft scope warning on anonymous object in version 1.5.0

[kyungminlee]

In Julia 1.5.0, I get a warning about ambiguous scoping of an anonymous object. Following is the shortest code I have found to reproduce this issue:

julia> include("f.jl")
┌ Warning: Assignment to `#s17` in soft scope is ambiguous because a global variable by the same name exists: `#s17` will be treated as a new local. Disambiguate by using `local #s17` to suppress this warning or `global #s17` to assign to the existing global variable.
└ @ C:\Users\kyungminlee\Code\soft-scope\f.jl:6

where f.jl is

function foo()
    f(lhs::Integer, rhs::Integer) = nothing
    f(lhs::Integer, rhs::AbstractVector{<:Integer}) = nothing
    return f
end
struct Bar{T<:Real, P<:Real} end

This only seems to happen when I do include: no warning is thrown when I put the code in a module and import it, or just type it in the repl.
