I have a .jl file where I define struct S that I call from another .jl file with using Revise; includet("path_to_file").

With this definition of S, I get ERROR: invalid redefinition of type S even when I'm in a completely new Julia session.

struct S{N}
    x::Array{<:Real, N}

    S{N}(x::Array{<:Real, N}) where N = new{N}(x)
    S(x::Array{<:Real, N}) where N = S{N}(x) # remove this and the error goes away
end

If I remove the second constructor, the error goes away.

I do not get the error, with or without the second constructor, if I use include instead of includet.
