Load error due to type problem

[bocc]

The following method definition

function FEMBase.get_integration_points(::Problem{Beam}, ::Element{Seg2})
    return FEMQuad.get_quadrature_points(Val{:GLSEG3})
end

causes the following error: LoadError: TypeError: in AbstractElement, in M, expected M <: FEMBase.AbstractFieldSet, got Type{Seg2} in version 0.3.1, with Julia 1.4.1. It seems to me that it is caused by FEMBase.Element having two type parameters, so supplying any subtype of AbstractFieldSet as the first type param resolves the issue. (If there is a way to ignore a type parameter, that would also work, since only the second is needed for dispatch, but I couldn't find it.)

function FEMBase.get_integration_points(::Problem{Beam}, 
    ::Element{<:FEMBase.AbstractFieldSet, Seg2})
    return FEMQuad.get_quadrature_points(Val{:GLSEG3})
end

To test this out, we can try:

e = Element(Seg2, [1, 2])
p = Problem(Beam, "example 1", 6)

FEMBase.get_integration_points(p, e)

This works, and produces an Iterator of tuples. (@which also confirms this method is called.)
