methods(TT)
call(::Type{TT}, x::Float64, y::Float64) at In[22]:2
call(::Type{TT}, x, y) at In[22]:2
call{T}(::Type{T}, arg) at essentials.jl:56
call{T}(::Type{T}, args...) at essentials.jl:57
So I guess the rule is applied in call(::Type{TT}, x, y)
What does it do? Does it try to convert(Float64, x) & convert(Float64, y)?
I.e does it always try to convert each argument to the type of the field
defined in the type?
