Hi, I am trying to overload getproperty for a struct I have. I do: function Base.getproperty(m::ABM, s::Symbol) if s ∈ (:agents, :space, :scheduler, :properties) return Base.getfield(m, s) else return Base.getindex(m.properties, s) end end So, my end goal is to still b…

Update! using: function Base.getproperty(m::ABM{A, S, F, P}, s::Symbol) where {A, S, F, P} if s === :agents return getfield(m, :agents) elseif s === :space return getfield(m, :space) elseif s === :scheduler return getfield(m, :scheduler) elseif s === :proper…

Fredrik suggested that I try instead function Base.getproperty(m::ABM{A, S, F, P}, s::Symbol) where {A, S, F, P} if s === :agents return Base.getfield(m, :agents) elseif s === :space return Base.getfield(m, :space) elseif s === :scheduler return Base.getfield(m, …

I would try replacing m.properties on the 5th line with getfield(m, :properties). This recursion could be the reason why your getproperty is not inferred here.
